Go left

You decide to find out if it was a warning or not. If not, great. And if it was, at least you're sort of forewarned. You head down the left corridor, pondering your next encounter. First naga, then centaur...another half-human creature, perhaps? A harpy? Or a satyr? Minotaur, sphinx, merman -- might be a bit uncomfortable for the last one, unless the tunnel was flooded. Of course, there was a dragon carved above the first doorway, which you have yet to encounter.

You've compiled quite a list of possible beasts and monsters, but as you come around a corner and find yourself standing before three of the ugliest creatures you've ever seen, goblins somehow never crossed your mind. One is tall - for a goblin, anyway - standing as high as your elbow, his skin gray and warty, his pale green eyes popping out of his face like a toad's. One is as round as a pumpkin, his stocky legs bowed to make room for his abnormally large balls, his skin as brown as mud with a damp, sweaty sheen to it. And the third has skin the color of swamp water, greenish gray and covered in black blotches. He is muscular, with long arms and short legs, rather like a gorilla with a skin disease.

They had been sitting in the corridor, tossing something back and forth between them, which falls forgotten in the dust when they see you. You glance at it; it appears to a dead rat, several days gone from the look of it. The tall one scrambles to his feet, his cock hardening instantly.
