Messiah

The Messiah is a warhead intended for use in Operation Jacob's Ladder.

Overview
Being developed over the course of 15 years, the Messiah was a bomb intended to destroy Gehenna in a single blow. It was ready to fire at a moment's notice, but was held on standby until a Gehenna Gate could be created to make use of it.

Launched from a specially built bomber, the order to deploy or recall the Messiah can only be given by Ernst Frederik Egin, making it a truly desperate device that can only be used when there is no other option.

Once detonated, the Messiah creates a pillar of pink light through the Gehenna Gate, however, it ultimately proved ineffective.
