"I will not have a pathetic mortal pawn like you insulting the legacy of my elder sister and Queen! She has sacrificed far too much and far too long to deserve that sort of abuse!" The flickering head leaned back, hissing with the assistance of dozens of dragonfly wings. "Tchern is righteous, but she is also stubborn. She doesn't realize that our combined strength alone is not enough to achieve victory in the Trinary War."
- Urohringr, "Destiny, Misery, and Your Mother"

Tchern, also known as "The Night Mother" is the sister of Changeling queen Chrysalis. She lives with her hive on the dark side of the world, and is one of the factions involved in the Trinary War. See Urohringr ch. 53
