Exactly.

Even tho i believe they could let us in, that gate from inside is still place good enough for ambush ... Zevlor would simply need to talk with us from a distance, while his archers would be positioning around.
Then, depending on our dialogue choice we would either get small (but conciderable) rep. bonus to all Tiefling vendors in town (aka discount ... wich is certainly nice) ... or not ... or we would even get rep. penalisation (aka they would dislike us, everything would cost more, we get less, and dismissive dialogues are unlocked).

People hating me for being a Goblin is part of the reason I want to play one, it's half the fun.
See? This goblin gets it. :3
