Sylas didn't mean that it was literally Azrael, though he wouldn't be surprised if it was. Considering Alex had "come back from the dead," it would be hard to surprise Sylas with such a thing anymore, especially considering Azrael, if Sylas was correct, was a member of an alien race.
'Another one, huh?'
Sylas couldn't see this person's stats, but he wasn't nearly as shaken as he had been in the past. He had an odd confidence about himself right now that was born through the battles that he had been through. Before, it had only been a small ember, but the more he fought, the fiercer it burned.
Running in this environment was almost impossible, so why not take advantage of the distance to recover?
