The breaking of the spell was temporarily stopped due to the rampaging monster on the east side of the forest. Alfein hastened his men to go back in destroying the spell, or they would not accomplish what they came there for.

Temporarily, Cronus can create a portal through hell. The activation of the spell requires a lot of time and mana, but once used, Cronus will have an army of haunting evil spirits.
