Well now I'm wondering why Triquel is in the prologue??? Unless it's just a dude who looks like Triquel. I was convinced that it was him though because it seemed to be far future when the monsters finally break out of the rift areas and start running rampant.
I mean, it might've been the artist trying out possible far future character designs and nothing was set in stone about their future yet.
In either case, Triquel didn't have that devil-may-care swagger about him that the dude from the prologue did, but I thought that just meant something radical happened to him in the future that caused a shift in his personality.
