Shemhazian Demon- True Demons level city blocks, so it was probably a Cambrion or some other half breed

Transmutation- This is another term for alchemy in this world, but it doesn't deal with Telekinesis, Shapeshifting yes. 

Its a type of Force Magic or in individuals with a Superior will its a literal manifestation of their Will in the world. Keeping in mind that Force magic is a separate school of magic so to speak. 

 bind mana- Magic on its own is simply referred to as Magic, Mana might be a guild specific term but from what I can tell the character is using Wild magic so he'll be drawing on the ambient magic of Galendar for all of his power as opposed to having it given to him by a God or an object. 

Aboleth’s Lung- get your D&D reference out of here lol they are called Abberants, but seriously name change is all with this one.


[i]Malakaus currently rents an apartment near the mage’s guild that also houses Annabeth. A fairly humble home, has your usual necessities as well as a personal desktop for Malakaus’s own use.
[/i]- This is fine though the Tower of Stars has its own Barracks for those who wish to live on sight. Keeping in mind the Tower should be a separate entity from the Mage guild.

Beyond that, and those are pretty knit picky In my opinion, the character looks good.
