|Given Name||Anathem Mire|
He led many expeditions into the caves beneath to study the Black Crystals, every time being the sole survivor. This may be because he killed his comrades so they wouldn't steal his secrets. He was known to punish people by throwing them into the deadly caves and died on his last expedition, but before passing he constructed a warped replica of his house in the caverns.
In The Faceless Ones Skulduggery kicks his corpse, awakening his spirit. He initially attacked them for intruding but calmed down and led them to the Black Crystals. As they were about to leave he trapped Valkyrie inside the house as he wanted to keep her in his castle forever to be his queen. She eventually evaded him and escaped the house which Anathem could no longer leave. The two left him swearing that he'd find her.
Valkyrie found bits of his body when she went through the caves to find Foe's Gang.
