"Alright," Maya began, "I'm going to pair you up and have you duel each other, Claire, you're with Tera; Blythe, you're with Israfil; Solomon, you're with Sion."

For the most part, they were matched up by firepower: both Asteria and Mayura were support-types, while Legion and Fury both used multiple, but weaker attacks and attacked from multiple directions to confuse overwhelm the opponent.  The mismatch was with Nyx and Orpheus, where Orpheus had significantly more firepower, though it did suffer in speed considerably.

The virtual combat arenas loaded up for each cog.  Initially none of the combatants could see their opponent as the simulated desert terrain was dotted with conspicuous mesas that cogs could hide behind.

This gave Mayura a distinct advantage as Tera activated the sensor array to locate Asteria's position, finding it easily.  Mayura silently made it's way towards Asteria, going from mesa to mesa, trying to make sure she wasn't spotted.

Israfil, on the other hand, walked Orpheus out into the open, and upon realizing that he couldn't find Nyx anywhere, began bombarding the mesas at random.
