Banshees

Elliot sighed.

He hated to admit it, but Gilgamar was right.

Foolishness was bound in the hearts of youth, and their hotbloodedness leads them down many reckless paths.

Apparently, Elliot was not exempt from that saying.

He had vastly underestimated the effectiveness and strength of his catalytic spell, and his resulting act of stuffing so many runes to the trigger for nuclear fusion had caused an explosion that far exceeded the energy capacity of the fabric of space in the Shadow Realm!

The shredding of the Realm Barrier between it and whatever "adjacent" realm was definitely another unintended and disastrous consequence. Whether or not it would ultimately be useful like Elliot's earlier unintended and disastrous nuclear fusion though, remains completely to be seen.
