Lady Midnight is a powerful, but mysterious entity who has been proliferating worshipers across Ahlim, particularly Rzeka. The Warriors of The West have heard much about her from a variety of sources, but her true identity and goals are still unclear. She is supposedly The First Warlock, a scholar of ancient House Valeng. She is also possibly Calamity, who almost destroyed Rzeka centuries ago.
What is known is that she has the alliance of many dangerous figures, such as The Crimson Matron, The Demonlords Orcus and Zuggtmoy, and mortals like Evangeliza. She is supposedly in opposition to Demogorgon and his demonic followers, but is certainly not an ally of The Annerians. The party recently discovered that she is Calee Valeng, known as Calamity and The First Warlock. The party reunited her with her partner, Hiromi, Mother of The Dragonlords. For several months she was known to The Warriors of The West as Khalida.
She recently Soul-Melded with Hiromi, becoming a two-headed metallic lavender dragon. She then supposedly went to The Destroyer and gained an Astral Spark. She is now known as the god Tiamat and rules The Nine-Hells.
