Hm. That might do away with my initial theory regarding this...head void. [head void sounds extremely stupid, but Pal can't think of a better name. He looks up at Skulduggery.] Is there anything unique about your bones that would make them more difficult than usual to destroy--are they preserved, or do they have regenerating properties?

[He makes an interested 'hmm!' when Skulduggery mentions the captain's mysterious soul vision (again, the name needs some workshopping)] Could you tell if there were souls that did not belong to the living passengers--ones that belonged to, say, the revenants trapped aboard?
