"Ifn' you think a bugbear be a sneaking, dangerous bastard. Well, friend. I've got terrible news for ya. They are even worse when they are dead. The gloaming gutter terrorized a human city for months on end as part of a goblinoid war party workin outta the sewers. She left piles of mutilated peasants n' took out heroes as they slept. When folks finally got wise to where the bugbears and gobbos were comin from, it became a bloodbath in the opposite direction. Not that it did alot of good, as the gutter got away... for a few days anyway. She was eventually caught, but not executed right off bat. 'Stead, they put her in stocks, letting folks pelt her with rotten food n' other things, giving her jus enough grub to keep her starving slow. Their cruelty made sense in the moment, but cruel deaths breed ghosts. Not that city's got a bigger problem, one that's haunted them fer generations."
