The Eight Snake Headed was All Lizardman below the Neck, Yellowscales Hydra.
"My Ssself-chosssen nick-name is 'Hydra-Nagusss,' most people don't ask about my formal name, Jadrec 'the Eight-Headed Yellowssscales' the Magus, but having yellow ssscales has nothing to do with courage. Yes, the usual reaction of hushed staring while you rally your Guardsss and Watchmen. Here is my list of desssired sssupplies and a pouch of gold more than twice needed. I will stay outside the town wallsss. And fill this Rum Ssskin with the good ssstuff you are known for, goodmen."
