Re-Awakening with the Summoner's Class

“Before the towers fell, before everything was consumed by darkness...”

Leo Astralis whispered to himself while traversing through the rubble of the ancient structure.

His body bore the scars of survival, bite marks that throbbed against the coarse, blood-stiffened fabric of his clothing.

A singular message urged Leo to escape, yet it was short lived as was he was caught like an animal in a trap.

And just like an animal he lashed out until the very end, taking one of the captors to the grave with him.

But as darkness closed in, the system spoke again.

[One time Regression activated]

[Congratulations. You've activated the Heart of the System]
