Adira, the Founder

Adira bint Dasia was unhappy with the way her husband was stripped of all his riches, and thrown into prison. She didn't think he deserved it. And she definitely didn't deserve it. And the new system, where everyone got an allotment of magic every month - she didn't like that. It was unjust and unfair. She had gotten used to a certain way of life, and she needed that back. So, she made a plan. It took a long time. She had to befriend people she hated. Had to enter people's homes, offer her services so she could figure out ways to steal their allotment of magic. It was years before she was ready. But with the help of her crew - the wives of the other men who'd been stripped of their wealth and position - she got her hands on a whole bunch of magic. Chaos insued, but they'd found a place to hide away and prepare away from all that chaos.
She ingested a shit-tonne of magic. More than anyone ever had before - save probably Basil the loser. But he's an immortal Kabir, and the magic has a different effect on different races. But she didn't have time to worry about that. While she did all the ingesting and magic, the other women worked on trying to figure out how to get their husband's free. Of course, males always underestimate women. So they were able to enter the prisons with magic humming in their veins, and nobody even asked a thing. They gave their husbands brewed potions - invisibility, speed, every other thing they needed, and their husbands escaped. More chaos ensued, but the women and their husbands were again hidden away.
More prep was made, but they were finally ready. They made their way to the docks - where enormous ships were waiting to take pilgrims to al-Ard. There were guards of course, but Adira was buzzing with power. She had so much magic inside her, she was glowing, vibrating, her hair was standing up. As the others commandeered a ship of their choosing, she raised herself high in the sky, gathered all her strength, all her power, her hands clasped together as the power built. Then she arced her back, spread her arms wide, and lit up the sky. Rain cloud gathered, but instead of rain drops, they released shards of ice, sharpened to extreme. They rained down on all the guards, slicing them up, painting the ground red. She floated back down to the ground, as the ice melted to rain drops, and fell to the deck of their ship. The guards were all dead and their blood was being washed away, seeping into the ground.
They took off, not waiting for more guards to show up. The trip usually would take days upon days, but with magic in their veins, they propelled the ship, made it faster than ever, and they reached al-Ard and started erecting the a-Jadar. But in the distance, they could see Basil had come to play. He'd brought a fleet, and they were all using their magic, throwing it at the wall and the island. Adira had regained her strength and flew back up to meet them, as the wall continued to build. It was a mighty battle. Basil threw all he could, but his downfall was his mercy, and compassion. There were people living on al-Ard, and it was also the home of al-Nahr. He couldn't bear the thought of ruining that perfect place. So he didn't go too hard. And he instructed the rest of the fleet not to either. They directed their power toward the wall being built, and at Adira high in the sky.
But it was no use.
Because, in a second, the island itself had started fighting back. al-Nahr, not being able to see what was happening, or understand the problem, did all It could to protect Its borders. It sent tidal waves against the fleet, and wiped it out in a manner of moments. The wall was built in a few moments more and, even though Basil had survived the attack from al-Nahr, there was no way he was ever getting across that wall. Not now with it's reinforcement from al-Nahr.
So, Adira and her crew were successful. They took over the land and people that were living on al-Ard, explaining that the world outside had died, succumbed to The Plague, and they began to build the kingdom of Inqaa. Later she found she was pregnant, during that whole thing. And she becomes really run down, passes the reigns to her husband, Kadar, for a bit. But she gives birth to Talitha, and everything works out. She gets better, and the kingdom continues to be built. Two years later, she gets pregnant again, and this pregnancy is worse than the first. Probably because she's almost 50. But also maybe because she has so much magic in her bones. Well, Eisa is born, but sadly Adira dies during labour. And, as Talitha is only two, Kadar rules in her stead, until she of age.
The kingdom of Inqaa mourns the death of their malika Adira, because she was a just ruler, and she gave them a world that was fair and beautiful. They didn't know it started upon a bed of lies, of course. She did banish the Fidayan people - but most other beings were happy with that. Those all-knowing, self-righteous Fidayans!
And that is the story of the founder of Inqaa, Adira bint Dasia.
