If there's a temple of Dol Dorn in town, I set up GAlec's background so he could actually be a local. If not, I figure the temple decided to send him out "on mission" in hopes that he'd finally burn himself out on this rebel schtick if he took a few good knocks along the way. The trip's taken him out by Greenblade, where he's stopping for a few days, trying to decide if they need him or if he should keep moving.
