In the cloying dark of a dwarven hold long lost to fang and claw, two degenerate tribes of furtive kobolds fight a brutal war of deadly traps and sudden ambush. Driven relentlessly on by their draconic masters, only the utter annihilation of one tribe will end this decades-long rivalry.

Kobolds of the Fallen Halls includes:

• Eight new feats
• Four new spells
• Two complete dragon hoards
• Twenty stat blocks (ranging from CR 1/4- 9)
• Full details of Antharuthux, a male juvenile black dragon
• Full details of Dereghwyr, a female juvenile green dragon

Kobolds of the Fallen Halls is inspired by Robert E. Howards short story "Red Nails."
