The Newcomers Conflict
Military action
When the humans first arrived there was a small time of peace for them. The western coast is mostly free of hostile lifeforms, so they settled there and went unnoticed for 7 months. However, once they were found out they had to move fast or face extinction.
Seven months after arriving in Idwala, the Human race began to set up a fishing village and already harvested a wheat crop. However, a group of curious halflings stumbled into their settlement. They ran back to their village and warned everyone what they had saw. Gnomes and halflings alike joined together to drive off what they thought was an invading force. On October 20, 641 TS gnomes and halflings lead a full frontal assault on the unsuspecting humans. Killing just under 1,000, one third of the human population, and the joint gnome/halfling army becoming overrun once the Humans were able to organize themselves.
After the assault the human race left there village abandoned, becoming nomads cross southern Idwala for a time. They engaged in guerrilla warfare for a time against the halflings and gnomes, who altogether refused to leave their village or properly fortify it. However, the goal of these raids on the village was not to kill, but instead gather supplies such as food, medicine, clothing, anything to help them survive in the plains and forest in the south. The gnomes however had a plan. The dwarven civil war had been carrying on for some time now, and one house was driven to the mainland at this point. They sent two parties out in search of allies, a group of halflings would try to beseech some dwarfs into joining their cause, and a handful of gnomes would seek out the dragonborn who were also nomadic people in the south.
Now the humans had already made contact with dragonborn, and assumed they were monsters themselves, as their myths and legends speak of dragons who took the form of humans and devoured them. When the gnomes eventually met with one of the tribes, the isolationist tribe could not help themselves from accepting the offer. The halflings on the other hand weren't so lucky with the dwarfs. But what is one to expect when you approach a dwarven army that has been stripped of their honor and in the middle of a civil war in full armor? Their negotiations, started and ended in conflict, several times, until Anora Inn, decided that maybe approaching without looking hostile would be a better tactic, which in fact it was. After making a truce with the dwarfs of house Berg, Anora had a stroke of wisdom.
After years of conflict, that amounted in only and equal amount of deaths on all sides, Anora tried something no one else did, talking with the humans. Approaching cautiously, but confidently, Anora came alone to speak with the humans, who at first were rightfully concerned. They allowed her to approach and although there was a significant accent barrier, there languages appeared to be different dialects of the same language, with a few major differences. Anora asked if only one human would come with her as proof to her village that they were not savages, but actual civilized folk, Aden Polo, a human who lost his family at sea offered to go with her. When the arrived to the village it was discovered that the humans were no more that marooned people suffering from near extinction after a cataclysm of their own. This ended the Outlander conflict, though relationships between humans and all other races were rocky for decades to come.
