Inside there was no Albus, meaning his preparation was in vain. Instead, he saw an unusual sight: a huge monster's skeletal remains. It took some time for Astor to make out the figure from the mess of bones, and at first, he erroneously surmised that it was a collection of long-dead creatures. The body of the thing looked mammalian; there were four feet, which could be determined by the usual metatarsal bones and their placement on the creature. A large tail at the back made one think of some kind of canine beast, but instead of one skull, there were three. He had always supposed it a myth, but the evidence here was indisputable; these were the bones of Kerberos.
