An Overhaul submod for The Elder Scrolls: Total War, adding many major features, such as new factions, new custom campaigns, alchemy crafting, events, Oblivion realms and portals to them, dungeons, lore missions and guilds, upgradable settlements, many new units and retextures, traits, ancillaries and more!
What kind of character is the ambitious slaver? General, merchant, spy, assassin?
Its a spawned general (on a ship, just to be safe). After the mission he will leave back home (the character will be killed via script) :)
Similar missions there will be for bretons/redguards vs orcs, assuming the player has a knight chapter (guild)
