Fighters Guild bounty quests in Cyrodiil. Need to spend a skill point which can only be spent when you have level 9 in Fighters Guild, it's a passive skill allowing you to take PvE bounty quests (goblins, bandits, necromancers etc.) in Cyrodiil.
Also, the inn from which you get them is in the *other* home area to all the regular Cyrodiil quests... for instance, for the Covenant, all the Warfront / Conquest / Scouting quests are in the South gate, but the Fighters Guild quests are inside the inn at the North gate.
What do you even get for those quests?
Don't think I've ever done one.
