The Bloodoak Tavern.
The Bloodoak Tavern was a Bloodoak-themed inn in Undertown during the Twig trilogy, run by Mother Horsefeather. In addition to owning the Bloodoak Tavern, Mother Horsefeather also financed many Sky Pirates, including Cloud Wolf and, later, his son, Twig.
The tavern was destroyed in the Dark Maelstrom, along with the rest of Undertown. Its legacy was continued in New Undertown, at the similarly named New Bloodoak Tavern.
