Klarth's eye isn't trained, exactly, given that the only time he really saw arcane body markings was when he glanced in a mirror, but he certainly does recognize them for what they are. How in the world had she managed to hide them so well? When he'd first begun inscribing the marks on himself, he'd resigned himself to a lifetime of funny looks (though, admittedly, they'd evolved into admiring looks as his reputation in Euclid had grown), and while he was well-familiar with his own reflection now, it still would have been nice to have the option of turning them off. From the brief glimpse he catches of Celena's markings, it seems clear that the design was different from his own. Not surprising, given that he was geared 100% towards enabling the ritual of the summon contract, but it was no doubt similar in concept.

...All of that is forgotten, though, as Celena finishes the incantation, her calm voice ringing clearly in the air even as the device flares to life. It is impossible to do anything but stare in stunned silence as the spell explodes forth; the sheer power of it seems almost tangible as it surges out to intertwine with the very fabric of reality, effecting a massive change in the ever-present streams of mana flowing all around.

Klarth gapes.

"I-Incredible.....! ...Quickly! We need to determine the effective radius before the base mana levels readjust!"
