Yarna Greatspeaker, Matriarch of War

Early Life and a Discovery
Yarna Greatspeaker started her life on the shores of the Eye of Geteema on a path to become a Priestess of the Triad (Arma, Geteema and Seedrik) and eventually a matriarch in the Lodge of Great Mothers. Her life took a turn when her travels brought her deeper south, in the borderlands between orcish terrritory, the goblinoid Badlands, and the so-called Shield Lands of the Dwarven Empire and its conquered peoples.  As she visited various villages and towns on those borders, she realized that something troubling was occurring on every side -- the people of the blood, even goblins and ogres, were going missing. Those absences quickly turned to entire settlements being overrun and emptied of people after signs of an attack shrouded in darkness. It was completely unclear who was at fault here, and Yarna suspected targeted attacks to cover some hobgoblin activities even against their own auxiliaries, subordinates and conquered populations. 
Yarna brought together what would be called a fellowship in the Shield Lands and beyond, a company in the Dwarven Empire. Because its members were the survivors of various brotherhoods, sisterhoods and circles from that region, Yarna dubbed it a crescent as their first meeting together was conducted under a waxing crescent. At the head of her crescent, Yarna moved quietly into the goblinoid lands to investigate the activities of the hobgoblin overlords. They went undetected for several months, enough time to determine that the hobgoblins were dealing with the same problems that they had been. Once it was confirmed that the hobgoblins were not at fault, she moved her people southward into the borderlands of the Shield Lands. When in proximity to Okar, it becomes necessary to move cautiously, much moreso than when in the Badlands or even the Lands of the Eye. Despite being conquered, the elves and half-elves of Othune guarded their borders jealously and responded to threats quite vigourously. 
Into the Shield Lands
It had been almost three decades since the great half-elven war-leader Fortias and the matriarchs of the Lodge agreed to keep to their own lands. For a generation, the Great Mothers had worked with their sisterhoods to nudge the great, uncontrollable hordes led by uncontrollable warlords in the direction of the Badlands and the Steppelands. Thus, two hordes had descended upon the hobgoblin hegemon Tezamir the Ninth in the past, and another upon the Nomads of the Steppes just recently, and there was no sign of another imminent. Despite that, the sentinels of Okar -- called the Torchbearers -- were still quite active in their enforcement of the borderlands. And so, Yarna had a choice. 
Going against her instincts, and the instincts of all but one of her crescent, she was open about her approach to Okar. Watched the moment she entered the borderlands, and confronted the moment she was close enough to the first stronghold, the Torchbearers responded with a proportionate force that only slightly outnumbered Yarna's group. She spoke with the sentinels, which included the Lord-Captain of the Torchbearer Stronghold. After initial exchanges and ritual oaths to abide by the rules of hospitality, they entered the recently-rebuilt stronghold known as Moonstone. The half-elves noted that Yarna seemed to have a spiritual connection to this place, and her reflexive familiarly with the fortress' idiosyncrasies. Over the next several weeks, the Torchbearers played host to the orcish crescent of Yarna Greatspeaker and they exchanged all the information relevant to what was happening in the border region and beyond. 
Correspondence with the Kingdom of Othune and the dwarven Governor of Grand Fork further south confirmed that disappearances and overnight annihilation of villages had occurred there as well, and that it seemed to be centered on the lands of Okar. It became apparent that there was something coordinating attacks from the wilderlands of Okar, moving quietly in the darkness. They could not determine any activities on the surface of these terrtitories, and so they came to the conclusion that the vast and largely-unknown subterranean region known as the Underdark was being used to shroud these activities. They had agreed to keep the dwarves out of the conversation for now, but they resolved that it would be important for the orcs and the elves to work together to find out what was affecting every living domain within a fortnight of travel. 
The Moonlight Alliance and the Fourth Great Horde
Yarna agreed to go with two of her most-trusted companions to meet with the King of Othune, who would arrange for representatives of the steppes and the elven lands to the south for aid. In the throne room of Othune, Yarna and the Lord-Captain presented their findings and evidence of what was occurring. The envoy from the Steppes revealed himself to be a Prophet of the One Faith, named Teroh One-Hand. A man of prophecy and vision, Teroh had noted that they believe that the evil that threatens the folk of the region now is reminiscent of how the Worm King and his minions ruled over the lands they conquered centuries ago. Both the representatives from the high elves of the Garden and the wood elves from Tannith agreed with this assessment, and they committed to send loremasters and delving specialists (dwarf fighters) to aid in the descent. Once the plans were all laid, Yarna stood and spoke an oath before all the others. Despite her upbringing, Yarna invoked Moya the Moon, Islan the Sun, and Yhera the Creator Goddess in her oath, which was reciprocated by all in attendance. Yarna and her companions returned to Moonstone, where she informed her crescent of the decisions. She stayed for a time, then took her leave with her companions to coordinate plans with the Matriarchs of the Lodge back home.
Yarna and her group returned to the Lands of the Eye to see that the Lodge of Great Mothers embroiled in emergency talks regarding the emergence of another horde of orcish warriors. It seems the various shores of the great lake had seen cohorts of orcish males staggered, and so each of the four "sides" had young men come of age at wildly separate times. This time, it is the southern shore of the great Eye of Geteema that has seen enormous warbands come together and now their leaders are fighting and duelling to settle out who will become the next Great Warlord. After telling them of her experiences and the oath that she had taken, the Matriarchs were taken aback. Unable or unwilling to send help in great enough numbers, Yarna was forced to show her anger and frustration. For her outburst, she was effectively shut out of decision-making in the Lodge without so much as a word. With no time to wallow in grief and rage, Yarna immediately took her crescent and sought out the place where the battles for leadership were taking place.
The Matriarch of War
Yarna found that there were now two great camps of orcish warriors. Bustling and roiling with destructive energy, the two hosts were coming together to watch as the two warlords arrayed themselves and thirteen each of their chosen champions to do one last melee to determine who would become the Great Warlord. Just as it was about to begin, Yarna and her crescent of twelve jumped into the great sand pit arena -- there they were joined by a singular wood elf from Tannith, who had followed them incognito. Yarna made her claim, and challenged the two others for leadership of the Great Horde. They agreed, and battle commenced. While Yarna lost five of her companions, she and her crescent emerged successful. The nine warbands proclaimed her the Great Warlord, and Yarna announced herself as the first Matriarch of War to great and thunderous support. Yarna gave her newfound army one moon to prepare themselves for war, and that they would all muster at the Fire Hills on the borderlands of Okar to bring honour and glory to the Dark Father in the name of the Wild Huntress.  
Yarna sent word to her Moonlight Allies to draw the enemy out once they were discovered. To feign weakness after being defeated underground, and to draw the enemy onto the surface of nothern Okar by the next New Moon. From there, she asked that a light resistance to her forces be kept in the forward strongholds but that they ultimately be abandoned and retreat made just ahead of the horde. The trap was set, and it was now up to the elves and half-elves to draw out the dark forces lurking in the Underdark. 
They were ultimately successful. It was discovered that the great Wightlord, Leshrac Blackheart, was replenishing the number of his undead legions of ghouls, ghasts and wights to once-again conquer Okar anad threaten Othune. Yarna's strategic feint worked, and the undead legions were once-again drawn out and onto the wild, rolling plains and dark, forestlands of Okar and its borderlands. Yarna's horde overran the Torchbearer's strongholds, and while some were destroyed, the horde kept moving forward. They met with the first signs of Blachheart's minions by the light of the waning crescent, and by the New Moon, they had surrounded the undead legions and drove them into the Underdark. 
Lacking not in bravery or rage, the orcish horde pursued Leshrac and his minions deep into the Underdark. They ultimately scoured the undead from the lands once again, but the fate of Yarna would be shrouded in mystery. Accompanied by her renewed and multicultural crescent, Yarna was at the tip of the orcish spear into the vast Underdark. It is rumoured that she found Leshrac and what remained of his elite guard of wights, and that they needed to sacrifice themselves to contain or defeat the ancient wightlord. The battle won, what remained of the orcish horde had lost its momentum, the orcs returned to the Lands of the Eye uninterrupted and they brought with them a great bounty of riches, treasures and stories of danger and triumph for their return. 
Posthumous Proclamation
After a year and a day, the half-elves of Okar and Othune, the wood elves of Tannith, and the Nomads of the Steppelands gathered at Moonstone to celebrate the life of Yarna Greatspeaker, the noblest orc yet known. The Torchbearers proclaimed her spiritual kin to their own hero, Fortias the Brave, and the Prophet of the One Faith proclaimed her a Sainte by their tradition, an incarnation of the Divine King -- the one who sealed the fate of Leshrac Blackheart and saved the People of the Blood from an age of darkness.
