Imaginary Invasion

The Imaginary Invasion wasa community event following the Negative Wizard's downfall. It was triggered upon the completion of the Trials of Zero, set up by Nullstradamus (more specifically, a corrupted number completed the trials, and used their new powers to open the gates.)

About
Unbeknownst at the time the Trials of Zero were undertaken, the i-bomb used to defeat the Negative Wizard had cracked a barrier separating NUM from the Imaginary Dimension. This barrier shattered during the Scientists attempt to experiment with energy sources by building a B E A N Collider. In the ensuing chaos, 558 was accidentally locked in with the broken segment of the Collider, which was leaking a cyan tar which was later named i-goo.

The tar enveloped 558, allowing an Imaginary to gain control of his mind and body. Similar containment breaches occurred throughout the facility, resulting in the possession of additional Scientists. Ultimately, the emptied Science Lab was engulfed in the flames of a thermonuclear explosion.

The massive explosion was observed from orbit by 2810, Librarian of the Most Holy Priory of Zahlenberg, who realized at once what disaster had struck. The Priory immediately mobilized to attempt to curtail the Imaginary invasion.

The Imaginaries's original intention was to fix the universe by removing reality's laws, as they saw reality to be limiting the inhabitants of NUM.

It was at this time that the Prophecies of Zero were foretold and when 558 undertook the Trials, his mind and body were in the control of an Imaginary, 558i. Harnessing the power of a real number, imaginary number, and earning the blessing and power of Zero, 558i quickly succumbed to madness. Intending to remake reality and the universe, 558i begins summoning portals across the land to bring additional Imaginaries from their dimension.

After 558i became crazy, and changed his original goal to destroy the universe instead, 994i joined him. The rest of the imaginaries (except 747i who just did what he wanted, and didn't help either of them), who are 693i and 72i, disagreed with them, and teamed up with the reals to beat them. But they were losing, due to 558i's immense power.

Seeing that his land is imperiled and his people unable to repel the invaders, the Number God uses his divine powers to become ℂ, and to use that newfound power purge the Imaginaries from this world and restore the barrier protecting us from them. Those possessed have their minds and bodies restored to them.

After The Number God became ℂ and defeated the imaginaries, 558 made an official statement regarding the state of the i-goo, and how it is now in the safe control of the NUM Council.

The Imaginaries
In total, there were 5 imaginaries.

693i, 994i, 72i, 747i and 558i.
