Adrian was not seeing things anymore because that sudden burst of lava was not an accidental or natural thing. If it was not pinpointed to hit him, the crater would not be at his general direction or area. There should also be other craters that appear to burst out if that were the case.
Adrian knew that the storm before them is not mindless like the other three that he first encountered. The Eye of the Storm looked like it was still looking at him and his soulbounds. It had the pressure of someone waiting for the other to move as if it was a predator.
[A Greater God of Wind Notus has influenced the storm with his powers.]
[The Lava Storm has gained sentience to be called a Living Storm.]
