Adventuring

So far we have completed a level 2 quest on accident and a level 4 quest intended for another party that were weak enough to succumb to these "evil gems." What is the standard of these adventurers? The ability to kill a sewer rat qualifies you for admittance? I hope this Barthel fellow can bump us up the ranks, so we can do more of these higher level quests. He seems to have some clout with these Adventurers, so we should do our best to win him over.
