Lieutenant (Tsuirakuan man)
From The Heretic Knowledge Vault
In context, not just any old Lieutenant, but one specific fellow who is ordered to take a squad of Heliomancers (basically, Tsuirakuan special forces) into Praenubilus Astu, to assist the elves in their death struggle with the forces of Ianilis. He's second in command (apparently) of this unit, behind Captain Aphel. He first appears here, asking high Tsuirakuan mucky-muck General Izayoi what is actually a very good question, when you think about it. (Sarine supplies part of the answer, in her inimitable style.)
He doesn't seem to do much on arrival in Praenubilus Astu, although his female counterpart does play enough of a role to get some "Appearances" credits.
He's at least made it beyond the "Ensign" rank (of "red-shirted ensign" fame), but guys like this have a most unsavory tendency to get dead when the shooting starts and/or the monster appears. Don't get overly attached to him.
