Where the Ego refers to the whole of a being's personality, the Shadow refers to a specific part that the Ego tries to ignore or reject. This is Raegal's Shadow; a legitimate part of who he is that he really doesn't like to acknowledge.

The astute among you may notice that the "Description" part is a wee bit different from the Ego layout. For Shadows, the "Description" is replaced with a tagline representing the nature of the Shadow, and the description itself contains information on what said Shadow represents. In this case, it'd be Raegal's reluctant understanding that being immortal means outliving your friends, thus making friends is just setting yourself up for torture later.

Also worth noting, as with the Shadows in Persona 4, all Shadows I draw have the trademark golden irises. I'd add the dark purple 'smoke' also characteristic of Shadows, but I felt that would detract from the overall design.

Jungian Psychology, bitches! Can you dig it?
