18. Here is one way to give your player characters a logical reason to adventure around the Keep of the Borderlands. I would have the king or queen of another tribe of kobolds, who live a seven days journey from the river valley tell the PC party this:
“An extended family of kobolds were deceived to move to the Caves of
Chaos. Then, once they arrived at the
Caves my fellow kobolds were murdered by an evil priest, to be turned into
zombie kobolds. I will pay your party
four hundred gold coins (can be negotiated to pay up to 800 gold coins) if you
destroy all the zombie kobolds for me.
Two of my strong bodyguards, Verdad and Falso, will join your group to make
sure that all zombie Kobolds are destroyed.
My two bodyguards will fight to protect themselves and your party
members in a quest setting my friends and family free from their undead
existence.”
