I’ll also say the Sethrak aren’t as unaligned as you say. They are part of Zandalar and are even present at Talanji’s coronation to leader of the Zandalari. The trolls of all backgrounds also pray to Sethrallis the Serpent Loa. Also they are quite plentiful as we see many at the temple, around the temple, all over Vol’dun, and we know they have cities beneath the dunes.
