The investigation adventure went fairly smoothly. Anyone have any advice on how to run a large military battle type encounter? I was thinking of giving the players about a half dozen NPC minions each to control as they help defend a fort. Current plan is to give PC with the flying mount a bunch of airborne foes to fight and goblin vulture-riders to command while the paladin rides to battle on his noble steed with either a horde of goblins(using a variant on the swarm template to make them actually a threat) or a bunch of fighters to control.
I'm looking forward to this one because I finally get to show some results for their decision to spare the enslaved goblin workers in their very first adventure: They've begun fighting to liberate their kin from the demons, with the one they not only spared but even healed becoming a "Goblin Shinyman"(using the Cavalier class) because he was inspired by the PC Paladin(who he calls "Shinyman 'Brek") to protect his fellows, because that's what a Shinyman does. Complete with cobbled together iron armor and a damn cookpot for a helmet. The players seemed to respond positively to the character before, so I think they'll get a kick out of his return.
