Anguish and Despair
The clattering of footsteps echoed out as a group a few thousand strong walked through a large tunnel. The tunnel was obviously carved by hand and was wide enough for the massive group to walk through without it being crowded. The ceiling of the tunnel was dozens of yards high, although some of the members of the group nearly touched the top with their heads, a testament to their size.
The group eventually arrived at a massive chamber, hundreds of yards wide, long, and tall. The chamber was empty except for an intricate teleportation circle in the very center, which was guarded by several monstrous looking creatures.
"Welcome," one of the creatures spoke out, his voice like the hiss of a snake. "Our master is waiting for you." The creature was a humanoid serpent, clearly from the monster race.
