Ghelgath's basically a lost dog at this point.  An abused lost dog that still loves his master for some reason.

I like Mephilus for some reason.  This reason has something to do with how he was partially inspired by Sliske.

Ghelgath was saved by him and his forces, so he aligns himself more with him personally.

A bit more cool-tempered version of Sliske I suppose, plus with his portal creation. Plus he's older slightly so.
