Trahearne is not the most beloved character in GW2, but Sieran is a strong competitor. For those of you who have not tried the Durmand Priory personal story arc, try the Durmand Priory personal story arc. Magister Sieran is your guide, and she is the happiest adventurer around. “Cherry!” (or sylvari cursing: “Thorns!”) We’re going into certain death: “It’ll be an adventure!”
Everyone gets the lesser version in the Pact story arc, Carys, who is enthusiastic about running in and whacking zombies with a big hammer. I tried this on a sylvari guardian, and it is indeed satisfying to whack zombies with a big hammer, so I can see why she is in such a good mood. Still, Sieran is the full version, the physical incarnation of joy and enthusiasm.
