Not seeing how he can help, unless there is need to batter the door down, Orsik keeps an eye on the surroundings lest they be surprised by local residents fearful of the temple.
Still, curiosity being essential part of him, he looks the door and walls adjacent over for traces of giantish inscription he could read.
Keke reports the sound of wings in the darkness and a glimpse of ungainly flying forms - perhaps half a dozen, each man-sized - as they flap away from the sudden light in the window and retreat into the darkness deeper inside.
Inspection of the door proves fruitless; the long centuries since its carving have taken their toll, and it's impossible now to tell anything of what they were once supposed to represent.
With a wave of his hand Mythra cancles the light on the window above. He then turns to the door. He makes a a gesture like turning a doorknob and it opens on its own.
The doors are heavy stone and appear to be wedged shut. Closer examination reveals that the hinges have long since rusted away, but still the doors seem to be held tightly in position by some means or other. Mythra's cantrip proves unequal to the task of prising them open.
Assuming there are no opening chimes or visible mechanism:
"My turn." says massive goliath as he pushes slightly agaist the door. Meeting resistance, he stops for the moment, lowering his maul for easy retreival.
"Ready?" he asks others.
If there are no objections he flexes his muscles and pushes with all his might.
OOC: Please roll whatever is needed, I'll assume Serris will aid, or use Orsik as aid another.
