Eventually, the dark wizard's physical body was destroyed. He felt no pain or suffering, other than frustration, as he was thus overwhelmed with great violence. Finally, Lucian vanished, seemingly without a trace. However, he unleashed a psychic blast, no physical force was expended on the protagonists, but the psychic scream was intense, leaving a message as he made himself loud and clear. "I cannot be destroyed! You are all damned!"
Meanwhile the portal grew with intensity. More people were unleashed from the Hell dimension to devour the protagonists. These people were all strong enough to rip cars to shreds, at least. Even those who were being destroyed could recorporate, eventually.

"What caused all those rifts in the first place? I assume it was tied to the sore loser in the black robes?" after a short pause to think he adds "If it is time travel then things should play out the same until one of us changes something, I think? Unless that guy also remembers what happened?"

"Well you have been making sense, and acting pretty confident, which is more than the rest of us can say, so kind of."
