Act 2: In Search of the Unknown Part I
OOC: No biggie. I'm going to assume it opens to the right, as that would give the majority of inside defenders the advantage since most people (not sure about goblins et al) are right handed. As it so happen, Uthecar is left handed (like every character I've ever played) so it serves him as well. If you want it different, it possibly makes little difference, but lets do it your way. :-)
Grabbing the latch mechanism in his right hand, he pulls back on the door, walking back with it as he peeks around. If he sees hordes he'll duck his head back, and continue to pull and walk back with the door pulling it wide open, before letting go and smoothly transgressing into battle. With the portal wide, his hope would be they are all exposed to ranged weapon fire.
If he sees one, or only a few, (especially if they are goblins) he'll just give the door a mighty tug with his right arm, so it swings wide open itself, as he then grabs his ax double handed shouting "Oorah!" to be shortly followed by "Az eron da Dwed". Ax of the dwarf as he bolts inside after them, mostly oblivious to such trifling dangers as being outnumbered. His fear at this stage is that with only a handful, his body count might be light before the range weapons strike.
