Ellsee: Search hive.
Upon entering his hive you notice that most of the items indoors have fallen to the ground or have been broken in some way, something really shook this place hard. That would also explain the hole going through his ablution chamber. It appears his respiteblock is no different, and even worse, he's still not here.
Besides the hole all that seems to be here are a couple cans, a chair that somehow got split in half, a weird looking box of some sort, and one extremely skittish custodian.
