There was also something about the Voyageuse being one of their number, and having been charged with leading their army. Has anybody heard more?
I think you're talking about the 3rd "script" (sorry if it isn't the right term) of the 3rd season of the Cronicles of Zaëbas : "The red breaker" in witch the "Voyageuse" was at the head of a templar army to put out off the "Wize Kingdom" the others factions.
