The Fairy Queen has fractured her kingdom and its subjects in twain, to spread the gleeful chaos of her kind to the world through the dual-kingdom of the Seelie and Unseelie. The Seelie, for all their mischief, and trickery are not a malicious folk, rather they are merely ignorant of mortal frailties. The Unseelie, however, are different. They are no strangers to the fragility of mortal lives, and, unlike their Seelie kin, actively relish in breaking them. However, their fey nature provides a fighting chance to mortal victims. Like their seelie kin, they cannot directly lie, only omit certain truths. But, for the less litigious mortal, they also share the same deathly weakness to cold iron. Both clans have become strange expressions of their hungers.
While Seelie fey seek to “Free” the mortal world by dissolving such stifling barriers as “law” and “convention”, the Unseelie fey are driven by a bone-deep desire to be made whole once more. They resent the fracturing of their courts, which fractured their nature and forced them to demean themselves by subsisting off mortal lifeblood. The true fear of all Seelie is that they might encounter their unseelie half and be devoured by their missing fragment, making a true fey once more... Only for the queen’s cruel decree to painfully split the creature into two entirely new halves.
It is odd, but true, that neither princess of either the Meadow Wilds Kingdom nor the princess of the Broken Ring Kingdom are the halves of the other, and it is unknown if their halves even still exist.
