TDO refusing to speak with the other gods (could be understandable or) could cast this in a different light. It's entirely possible that he does not *want* simply to negotiate for better treatment of the goblins, but actually wants to shift a gate to the outer planes to negotiate for his own power. He IS an evil deity, after all.

If that turns out to be the case, I'm not sure his interests align with Redcloak's. For all his faults, I suspect RC really is in it for the good of goblins. So, things could get very, very interesting.
