So in regards to tonight's session, Laucian is like Robbin hood in fact (as the Harper's have been described), but he's more realistic and more selfish. He doesn't wear tights and he's going to make himself comfortable in the process of conning rich people. His neutrality in regards to good and evil means he does some good and some bad; it balances out and always serves his own purposes. Me (and consequently he) were led to believe the Harpers Faction were Neutral as he is, maintaining balance, so he was comfortable and confident with joining them.
This page about the Harpers
describes them as simply good, but not necessarily lawful. I'll concede he's not the best match for them. He sees his cons as a redistribution of wealth from those who can afford to lose it. He's not trying to harm anyone he cons (not truly) and he does want to help some people, as long as he maintains a comfortable lifestyle that suits his goals.
Laucian is an egalitarian (relating to or believing in the principle that all people are equal and deserve equal rights and opportunities); I've probably stated it a dozen times over the past couple months. Egalitarianism is definitely a Harper value.
Also, let's not forget Laucian has gained some renown as a hero in this land. So-what that this gnome has some suspicions that he tried to con a rich guy. I'm not convinced the Harpers would see this as a big deal, given the context and their available knowledge.
I'll go with the flow no matter what happens. I just thought I'd explain more about who he is, and why I was caught off guard, in case there were misconceptions. @AdmiralMurphy
