Do not read this is you're going to play Long Arm of the Hutt as one of the PCs.
We're soon through the first act of LAotH. So soon this Ota NPC is going to show up. But there's now explanation to whom he works for, why does he want to help the PCs and what's in it for him? I gather that he is trying to make Teemo's life difficult, but why? He is very helpful, but how does he know that going to Piddocks party will help PCs with their bounty against Teemo?
I'm thinking of giving him some other motive which the PCs should use as secondary objective in the party. How did you play this out?
