Thanks guys.
Fighting mind flayers should be enough of an incentive to keep the party together, but they shouldn't have to be right in front of them. Now , I admit, I've stirred the hornet's nest myself before. And I've got some eeevilDM ideas for the future that may stir up the rivalry some more. Still, the party, and especially Du'minh and Jhank'kor, need a strong leader to keep 'em in line, and I'm sure that the situation we're seeing is fairly comman even within a warband, but the officers are there to keep it under control. So, you've now got an NPC captain, who might not be accompanying the party, but just having a leader-type to report to may keep these giths' minds on their duty rather than on fighting with each other.
Will do, boss, and many pardons to you both!
Hmm, I figure slaying illithids may not be the only incentive necessary to tie them together in the long run, considering how both characters seem to have been written with explosive tempers and a mind never to back down. Perhaps we ought to invent a background incentive that could soon come to revelation?
How about discovering they are actually part of the same band, seperated by some unusual occurence? (or just general chaos in the wake of the Queen's death)
