Euchre

Euchre is a 21 year old white haired Keidran who leads a double life as a Templar and ally to Trace.He is also good friends with Flora.

Euchre is seen as a "Master Strategist" when Lady Nora tells Trace that after he claimed title of Grand Templar, he made his own inner-circle what includes Master Spy, Architect, Strategist, Seer and Mage. Euchre seems to be the Master Strategist, also he's seen as a human at one part of the comic, when Trace is seeing something in his memory when they have arrived the Basitin Islands, he sees the scene where he tells the other (Masters i guess) that they should not care about Basitins and they would rot them from inside with the Templar Tower (which's build was lead by the Master Architect which Trace kills in Dark Magic - Enrage)

Euchre can also be the one who caused death of the Basitian Arms General but it is only a maybe. It also could be the Master Spy.

Life as Euchre
As Euchre he is a kind, helpful and cheerful person.He is very protective of Flora and will not hesitate to hurt Trace to protect her.But he is very helpful to them when he broke demi-god rules to help them defeat Ephemural who severely hurt him. He later showed up at his former masters/fellow Templar's home.
