Okay after skimming the pdf for 20 min here are my suggestions on what to take.
My suggestion is for class, pick champion. For starting advances I'd go with disturbing voice maybe to match Dranon's damn scary visage. Then for prides pick either fortitude or Martial prowess as those seem to fit better. For disgrace I'd pick Wrath as Dranon always gets a raw deal from the universe. It's not clear what modivates Dranon so I have no idea what to pick for the modivation chart. As for alignment advance, I'd start of unaligned, as word bearers don't favor to any one god.I'd then pick a few advances like abidexterous, counter attack and other melee skills to play up the only implied way Dranon fights. I'd also go for double team so you could get help from minions such as cultist chan in a fight.
That's all I can figure out right now. Don't forget to speak with the voice of a chain smoker! Also I'd talk to your GM about cultist chan and the whole eternal respawn to troll Dranon thing just in case he doesn't know and might get butthurt about it or something.
