Cael
Cael gives the mage a few more thwacks to make sure it's dead, and keeps using his blindsense to make sure no one else is near. He will then go back to his regular human form, pull out a wand and use it on himself twice, before putting it away. Once healed and assured no one is nearby he will order Broddie to stand guard while he searches the corpse. Once that is finished he will check out the passage where the caster was hiding behind the illusory wall, if it seems to be a dead end he will continues the way he was heading originally.
