So I told Eothas, "Hey Eothas, break the wheel and kill everybody so that entropy wins."
Eothas be like: "Fuck you, bitch! I'm just gonna do my own thing and break the wheel now. Rymrgand sucks!"
Great C&C there guys...
Pretty sure you can convince Eothas to destroy Eora.
As one of the comments suggested, might have something to do with Eder and/or Xoti not being in your party.
Yeah, that’s the ending I was going for and both Eder and Xoti were in my party.
Eder complained and told Eothas not to do it.
Xoti was Dark Xoti and told Eothas she agreed with the Watcher, and that Eothas should go ahead and permanently kill everyone after breaking the cycle. Eothas said he hated what Xoti had become.
Not sure which one screws it up, but after that he just breaks the wheel without killing everything else.
