Sinthus is what elves consider the capital city of Yi’Lillith. Even half-elves are scarce and anyone without elf blood does not enter this city without a personal Writ from the Elder. As barbarians from the north started encroaching upon the woods, Sinthus commissioned the installment of a military base between itself and the cold lands. That installation grew into the city of Pelson.
Elder Leyonnela is matriarch to all the elves in these lands, and head of Sinthus.
