For time unmeasured the Elves and Demons have warred with each other. The Demons have their strength, their cunning, their aggressive dominate nature that leads them to believe everything they set their eyes on is just waiting for them to claim it. The Elves had their magic, their wisdom, their patient nature that lends them to think they have all the time in the world.
Irdil was a warrior second but a princess first. She'd spent long years batting the Demon's who fought to lay claim to her fathers Land. His kingdom was large rich with natural resources. Unlike the Demon's Idril's people couldn't have children as fast as the Demon's so after years of war they were overwhelmed by sheer numbers.
With the king dead and the queen slain the Demon general forced his hand and demanded marriage of Idril, a compromise of sorts. She could marry him and save her people or deny him and see them all put to the sword because of her selfish behavior. She would be a figure head on the throne she'd been groomed to rule from, a puppet toy to a monster that disgusted her and a breeder of monsters. The idea repulsed her to no end but he'd made it clear without her complete and utter cooperation her people were simply fodder to him and of no consequence.
For his part despite the obvious appeal of not ripping the entire kingdom to shreds forcing him to spend long years rebuilding it eves were creatures of magic that Demon's couldn't touch, a mingling of the races would give them more power and Elves were the only other race that could carry a Demon child to term. Elves were known for their beauty an assets that didn't to escape the Demon's creatures that are prone more to their baser drives, sex being one of them.
