I just, really like the Hobgolbin design in game, it's true to the books but it looks great. So on those grounds, a Hobgob would be great. They could a prisoner of the bad guys due to disobedience or politics or something, maybe they were chief of a goblin band that joined the cult and edged out of power or just, signed up then didnt like it or who knows. Just, you rescue them and they're like oh I'll help you bring them down cos I hate them then we'll go our own way and then by the time you've done that your friends/comrades?

No tadpole, no romance, just a Hob who joins the fight and finds they like you. Maybe LN rather than evil? followed the rules and norms of Hobgob society but never really cared about them just was about doing whats expected, until it backfired in his imprisonment and how he's all, that's not right you know, that's not right but no good-evil concern about it?

Minthara is the best character and she NEEDS to be recruitable if you side with the grove!
Also- I support the important thread in the suggestions: Let everyone in the Party Speak
