It turns out a pair of Ultima V/VI characters are also TCS Tiger's Claw fighter pilots! If you boot up Wing Commander I's arcade TrainSim, you'll see a list of other players and their high scores. Two names that may appear are "Sutek" and "Seggallion"--who are both NPCs in Ultima V and VI! Sutek is a mage in Ultima V who loses his mind in Ultima VI. In Ultima V, Seggallion is a retired pirate... and in Ultima VI he is a knight from another world trapped in Brittannia who can accompany you in the game (going even further back, he originates as the main character in Origin's Knights of Legend). For good measure, a star in Wing Commander I's Vega Sector map is also named Seggallion! He gets around. You can learn more about both characters (including information on their appearances in other Ultima games not yet available via GOG) at the Codex of Ultima Wisdom.
