Lenya sees the old hobgoblin with a staff walk out of the doorway.
Everyone sees an ogre exit the Temple, a 9 foot tall, 1000 pound Ogre covered with thick black fur, long arms, and a broad muzzle. The Ogre seems well equipped with claws and teeth. Belaver recognizes the 'ogre' as a Dire Ape.
Lylamwyn casts his Fireball, catching the ten hobgoblin warriors on the stairs (two with heavy armor), the shaman, and the 'Ogre' in the blast radius (dmg 21, shaman save 16+3=19, 'ogre' save 14+6=20). All ten of the hobgoblin warriors are dead or dying. Craven (12+), Raner (4+), Toriah (18+), and Xaod (10+) shoot arrows at the Ogre, Toriah struck the Ogre(dmg 6).
The burned, severely wounded Ogre flees back inside the Temple. Lenya saw the singed Shaman follow the Ogre into the temple.
Kerwyn sees the hobgoblin sentries near the gate duck down back into cover. There is a lot of whining and howling going on. Seeing as the door to the Temple is now open, Kerwyn enters the temple to see what is going on inside.
Kerwyn sees another dozen hobgoblins, half in heavy armor, advancing towards the Temple exit.
