A Suitable Opponent

The opponents you train against in the coliseum are not physical beings, but rather manifestations of such. Your first opponent is one you and your soulbinds have met numerous times before -- the Ascended Kalisthene. Asking another kyrian to be your opponent in the Path is a great honor, as it tells them that you have much to learn from them. Go to Aspirant's Awakening and use the cores to summon Kalisthene by calling back to your first introduction. It is as ceremony states.
