This hole that had been hidden was revealed as it was among the last part of his body that was turning to stone.
One of the talents given by his Endless Vault Meditation Art was the ability to turn into data.
This state was unique and Andar had not been able to decipher the mysteries involved, but he knew that while he was in this state, he was not made up of energy but something in between energy and solid mass. Among all the things he had hidden from his masters in the Black Tower, this was one of them.
When he was in this state he could "Refresh" himself, this was another unique and overpowered ability that would heal him from any wounds and return his energy to the peak. The best part about it was that he could do this Refresh, nine times, effectively granting him nine lives.
