Hall of Infinite Doors

You stab at the creature with your short sword through the bones. It squeals in pain and surprise. You lift your sword and stab again, then again, until it cries no more. Black blood stains your weapon. You wipe it on your shirt, then you continue south.

After about an hour, you come to a great chasm. You look down into its depths but see no bottom. Something catches your eye, however. A dull, yellow glow shimmers in the blackness of the chasm. It is obviously very far down, and you don't know how you can reach it without jumping. You look left and right but see no bridge.

Which direction shall you go?
