Here is one of the final characters, a supporting member of the cast named "Zen-El"; he's basically the closest thing to a doctor that any of the inhabitants of Korsun will encounter.

Here's a brief description of Zen-El:

Zen-El is a former corner from DrakkenGuard (the home world of the Dragon race). Zen-El was quite content with his former occupation; however, during the final years of the war between the Dragons and the Volterran/Soldien coalition, many personnel with medical training, such as Zen-El, were drafted into the medical corps as a desperate attempt to stem the tide of casualties as the war effort became increasingly desperate.

The sights and experiences on the front-line were quite distressing for Zen-El, who was used to the quiet and solitude of his former occupation; he had a great deal of trouble dealing with the inevitable loss of patients and seeing the devastation of the war first-hand.

After the war, Zen-El wasn't sure he wanted to be a corner again, so he wandered frontier worlds and found that trained doctors were in short supply. He now lends his services to anyone who can pay even a modest amount and is willing to disregard the fact that he's a dragon. This typically means that he doesn't receive a lot of patients unless they've exhausted all other alternatives first.

If Zen-El has any flaw it's that his "bed-side manner" is still quite dreadful; he'll often recollect stories of his corner days when applying treatments or will make cadaver jokes (much to the dismay of his patients).
