In the ruins of El-Amara there exists a magical trap that is intended, when tripped, to summon four demons and eight anarchic vampire bats. It has been buried beneath the ground for a thousand years, and when tripped, by a fox looking for a good place to nest, it instead summons an axiomatic lemur, eight slugs with no discernable alignment or magical properties, and one human and his magical horse companion.
The wizard responsible would express his regrets but he's dead and also wouldn't have any regrets, mostly just fascination.
