This old family crypt of a forgotten noblehouse was once tended to with great care and respect. One day some of the aged brickwork could no longer support its own weight and collapsed, fracturing the floor. Kobolds then flooded through the newly opened holes, claiming the old crypt as their new home.
Since then noone dared to enter the crypt. The kobolds are fond of their new home and ready to defend it. Their leader robbed every single gold coin and other objects of value from this place, collecting them all in their room.
Adventurers might be tasked to drive out the kobolds or convince them to leave. Maybe someone was captured by the kobolds and needs to be rescued. Upon encountering them the koblolds could task the adventurers with destroying a restless ghost, that is haunting their tribe since arrival.
