Some background for Ulfgar and Orcassm:
[sblock]The attack on Greenest came suddenly, with little warning, in the early hours of the morning. The first wave was of hardened warriors flying banners of various mercenary groups. The town militia and guard stood little chance against well disciplined and equipped fighters.
Soon after the initial assault, warriors, scouts and mages from many different races swept across the town; unlike the earlier force, they all wore the same garb - armour and robes fashioned to look like dragon scales and wings, helmets shaped like dragon heads. Occasionally you would catch glimpses of important looking figures in purple who seemed to be directing the attacks.
They concentrated their attack on the richer, noble houses and especially on the large temple of Tymora to the west of the town, near the main keep. You have no idea if the temple still stands.
Then came the kobolds - both on foot and on the wing. They looted indiscriminately, setting fires, killing any survivors they came across. Some of them herded huge reptilian drakes the size of a horse through the streets.
Most of the townsfolk had fled to the main keep during the attack, and it would still appear to be the safest place to be.[/sblock]
It would make sense to assume that you both know each other at least in passing. Ulfgar would presumably make a visit to the Dwarven temple on his occasional trips into Greenest to resupply.
