This seems like a perfect Homebrew Map for the Citadel of Might. Run by the Order of Iron Might, the Citadel looks like a fortress, sports a central court where people can train, plus it has an armory, armorsmiths and weaponsmiths, and even has lodging and meals. This Adventurer’s Guildhall map by Tom Cartos seems like a perfect fit!
From Tom Cartos: Those who are successful in their application gain access to the Guild’s training facilities and masters, free accommodation and meals whenever they are in town, the guild mission board, secure storage, extensive library, priest, in-house blacksmith, artificer and apothecary and financial services such as monetary exchange and loans, among many other perks and boons.
