=====

Fangorn is a dangerous beast. By day he hides, his “coffin” nothing more than a trench covered with a log. By night, he is the terror of the marsh, devouring anything in his domain; boggards, lizardfolk, crocodiles, and even unwary black dragons are meals for this monstrosity. Drained husks litter his ever-widening territory, and while many have attempted to slay him, those used to hunting hydras are caught off-guard by the beast’s surprising cunning; his better-than-animalistic intelligence has allowed him to learn how to construct simple traps, allowing him to dispose of would-be hunters largely at his leisure.
