Burbage says:
Given that they are well-known bandits, this might pose some ethical dilemmas for the lawful members of the party (Luther, Fenwick, Gabbro, Jessica), depending on what Gnast expects of you.
...not to mention the agreement we have with the Open Sores orcs, or the fact that we ambushed and brutally killed two of Gnast's gang already (whose corpses, it shouldn't have to be mentioned, are the source of the bad smell we keep detecting every time we go past that pit).
For Gabbro, adventuring is not all that different from the political infighting in his extended family, which has surprised and mildly disappointed him. Still, he shouldn't be surprised, given that there are creatures living here. It's more interesting than if all of the old prison was abandoned. But that doesn't help him navigate this particular situation of alliances and betrayals.
For me, it seems like we could:
- just try to deceive Gnast and join up with the Ghost Beggars, masquerading as bandits, with the idea that we'll maybe, eventually, learn about what Gnast is trying to find (and thus fulfill our previous quest)
- offer something of value (a service, perhaps?) in exchange for the information we want
- be honest and say "we've been hired by the orcs to do this thing" with the idea toward being mercenary, saying that we're open to offers to look the other way or even double-cross the orcs
- feed them dishonest information, in the hopes of orchestrating a confrontation between the Ghost Beggars and the Open Sores ("We heard a rumor...")
