The corridor turns sharply to the left. At the corner just before the turn, a peephole is carved into the stone wall at a height of 6 feet.
The peephole forms one end of a 5-foot-long tube cut through the solid rock wall.
As you fly west you realize the corridor ends at a block of stone on which is painted a seven-foot-tall jackal-headed humanoid with a circular gold medallion around its neck. All around the figure are carvings of locusts.
You discover also a crawlway north turning east.
OOC:
Unlike other times I will reveal you more details as you describe your interaction with environment such as make close inspection of any object/painting or try to look through the peephole. Feel free to include perception, investigation or other skill checks that you think best represent your action.
