The true drake characters (I was building 5 of them) are all prime runners opposing my players. I managed to work around them by saving them and then manually editing their .chum files to have lower essence ratings (6). Its a pain in the butt but it works, and since they can't have cyberware, bioware, geneware, nanoware, or symbiont's anyways (true drake prevents them taking anything that costs essence) it won't be a problem unless they run into a vampire.
The dragon was being built as a Big Bad for the players to be aiming at. He's gonna pop up from time to time and mess things up for him. The reason I'm trying to put him at essence 12 (max for a dragon) was so he can be *HEAVILY* cybered, but still have a decent ESS score. I can leave him at 8 and it'll probably work, but I just wanted to see if anybody had any ideas.
(Edit) now I kinda wanna try building a dragon cyborg >.>
