create alias tirugu_(tales) -> tilg_(tales)
No one seems to agree on how to romanize this character's name. I've seen Tilg, Tirgu, and Tirug, all of which could be claimed to be legitimate romanizations of ティルグ. I could not find any official sources online for the official romanization and couldn't find any evidence of him appearing in any English localizations. However, he did appear in Tales of the Rays (after the global version shut down) and his asset files contain the name Tilg as shown here. Most of the other characters' asset paths contain the official Japanese romanization of their names, so I think it's likely that Tilg is the official romanization.
