Does sound like the Thralls got you drunk on Firewater and “left you to your fate” 
He pawned your gear and weapons in the unnamed city and found some unnamed girls for the night .
The waking up naked part would make me the most nervous … I have seen deliverance!
He was like yeah bro remember that wheel of pain well when you log off it’s gonna be the feel of shame.
If you get to a thrall village and they all laugh and point at you then you’ll know for sure something bad happened!
Even though you cant get to the main hand slot on a thralls, if you equip the weapon on their armor slot, they equip it. Be sure to load the bow with arrows first!
