So I was doing the "No Stone Unturned" quest and I went to the Flagon one day when I was doing the quest and it turns out I had done something to get kicked out. So what could I have done to be kicked out as the Guild Master!?

Off the top of my head? Killed a Nightingale of Nocturnal, framed another for the crime, stolen the Skeleton Key, and then systematically emptied the vaults of the Thieves' Guild to increase your own wealth?

I imagine that would get the Guild Master kicked out, but who knows...


On topic though, I have no idea. Did you steal from someone or assault them?

I might have assaulted someone or framed. But I did complete the main quest ages ago.

The thieves guild are a bunch of losers. Just go back down there and kill 'em all like the rats that they are.

Did you assault the black-briars, fences or that guy in honningbrew meadery?

The only thing I can think of is pretty much what others have mentioned. Did you kill one of the marks on a job or kill/assault one of the other members?

Killing a fence is the only way I know of to get the guild to turn against you.
