Joe Corroney made those, he's good. I nearly had him draw some of the Star Wars RPG characters for me, but I was flat broke and he said something about prices...
Anyway, here's the list then...
Grand Admiral Tigellinus
Grand Admiral Syn
Grand Admiral Grunger
Grand Admiral Pitta
Grand Admiral Takel
Grand Admiral Il-Raz
Grand Admiral Makati
Grand Admiral Batch
Grand Admiral Grant
Grand Admiral Zaarin
Grand Admiral Teshik
Grand Admiral Declann
Grand Admiral Thrawn
sup all,
nice list for grand Admirals few people i know actually know them, although there have been various self appointed "grand admirals" after the collapse of the empire and capture/ death of the actual GA's .
also to note i know nothing of GA Zaarin since i dont play SW Games much, but since there is no conflicting evidence by movie book or comic i guess he can be let exist in the expanded universe, but you guys need to now that the games are meant for entertainment and many game story things are written by people who know squat about SW, like in one game Anikan had to destroy a "force harvester"...yeh force harvester my ass. but since there is conflicting evidence i cant say anything against Zaarin. also GM tesik was portrayed a bit different in the comics.
also Palleon wouldnt disgrace himself anointing himself GrandAdmiral until he though he could almost begin to rival the military genius of thrawn his former "teacher" of a sort
