i'm curious, what are the differences in character of Nathan's wolf self and Ardenu, his evil werewolf self?

Can you be more specific what you're asking? I've been trying to formulate an answer and I need a bit more direction.

the mental ones ( attitude, way of thinking) and som of the physical ones since i think i get the moral ones from our talks in Discord

Nathan's wolf form is basically the same as Nathan as a human, in terms of mentality. It's really just a different skin I get him drawn in sometimes. Physically, he’s a slight bit stronger and more agile, but can’t see colors as well and generally is less well balanced because of digitigrade stance versus plantigrade.

By comparison, Ardaenu is stronger, faster, and built out a bit, particularly since the werewolf he’s based on surpassed humans in several areas. Mentally, he’s more “Might makes right” and “Ends justify the means” as opposed to normal Nathan who is rather idealistic in general, if a bit tempered in reality.

Basically, Ardaenu is a dark mirror version who, when offered a chance at power in his story and to change sides, ruthlessly took it. Hope this clears this up for you!

I ser, thank you
