Knight- Orinoko, Seer - Babidi, Thief - Narissa ( who could be a better thief than the one that cracked the storehouses of the gods?), Sorcerer - Threap (before his divine crutches, IE Gems, Crippled his brain), Ranger - Pahn, Bard Culinane, Loremaster - Allanon or Zenichiro in their prime, mage - Fistandantilus, the only successfully mobile mage.
Oh and lets not forget most importantly, Animist - Mestopholies, the only one who has decomposed enough folks to qualify for fighter status.
if it were a list of most memorable I would put Nafai for sorcs, dreeman tfor Thieves (or plaman :P), Kes for Knights.
Written by my hand on the 4th of Eleuthral, in the year 1144.
