The Innkeeper behind the bar of the SkullBreak Tavern (Arsenal District) has no known name. He can provide a few consumable items for sale (Order something dialog choice.)
Goods for SaleEdit
Like other merchants, the Innkeeper can also buy unneeded items Scarlett wishes to sell, converting them to ducats she can spend on more useful items. (He will also be able to sell back to Scarlett any items she previously sold to him, though at a substantial markup price)
The Innkeeper himself it is not related to any Quests. However, his tavern has several people who can offer Scarlett some optional Quests to increase her Experience and Reputation, and one mandatory quest.
