Ylaya was a Keeper of the Law of the Shadowbrand Clan. Trouble rose when the dark elves began to be dissolving after Raelag mysteriously disappeared. She spied and learned Thralsai and Shadya were the ones who wanted Soulscar Clan revived. She went to search for Raelag and found he was with Isabel. They joined together and defeated Thralsai. Raelag went to search for Isabel's child, while Ylaya and Isabel went to liberate Horncrest and find shelter. Ylaya promised to fight Biara and her plans.
Later, she met Zehir, who attacked a rival clan, disposing of her troubles. She went to Talonguard and attacked Biara's troops. When it was all over, Ylaya returned back to Ygg-Chall to continue working as the Keeper of the Law.
