Daimon saw the Skelefiend woman who he captured, be in a really miserable state, due to the creativity of the queen to interrogate.
Skelefiends had two different evolution paths, they could develop flesh and get a human-like appearance, which is the path Shirel chose, or go for the mummified corpse appearance like Horrorclaw.
Their appearance in fact shows the path they have chosen to get stronger, those who become human-like are mages, while those who become full body skeletons are knights, in other words, Horrorclaw became an Emperor rank through the knight's path, the first one Daimon knows off having done it like that.
Maybe the mage path is easier for Neptune's natives, but so far, all the other Stellar ranks he has met are mages, a subject he has taken note and decided to talk with Vincent later, for now he saw those yellow crystal chains restraining Shirel and then turned to see the queen.
