okay so I killed a chicken in riverwood so the guards started chasing me and stuff, so I quick travelled to whiterun to realise that they attacked me too.. so I ran away from them but sort of killed like 5 guards in the process, and I don't really want to pay their like 2500 bounty so I was wondering who I had to talk to in the thieves guild to pay it off, i've done the main thieves quests in that i've done all the mercer quests and stuff that lead to you at the sepulcher (tried to avoid giving too much away) but I still can't find someone at the guild that gives me the option to pay off my bounty, any help?
