Hearing the howling signal, Ryze quickly crushed the teleportation crystal with his hand.
Anticipating the potential dangers of being so close to the Executor, Rex had already readied a safe route to escape if deemed necessary. It was through a special teleportation crystal, unlike conventional ones, was able to bypass dimensional locking spells.
It's recommended by the System, knowing the Executor's chaos elements is able to do that.
Ryze was still searching for Rex when this happened.
Despite trying his hardest, he couldn't find Rex's trace anywhere around the encampment.
He doesn't know that Rex made the place he was in with Gistella secure.
Suspecting Brigitta's certain tone to be bad news, he searched for Rex fearing that he might be lured into something that the Executor prepared for him. From the start of arriving in this place, he already felt uneasy, feeling that something might go wrong.
