As days passed, filled by cold darkness and grueling battles, Sunny had not only been slaying terrifying abominations and enduring the pain of his titanic form being torn to shreds. He was also slowly learning more about the Underworld — and especially about its history.
The Spell was stingy with granting him Memories, let alone Echoes, so he had not received any information from their descriptions. He had, however, gained quite a bit from the description of the shades he was gaining. Mostly, Sunny learned from exploring the crumbling waystations they were conquering.
One could learn a lot from careful observation. Even if thousands of years had passed, destroying most traces, there were still signs left of what had transpired here. For example, it was clear that the waystations had been meant to house far larger garrisons, but were left with only skeleton crews to guard them — the size of sleeping quarters and the armories did not fit the number of the corrupted Stone Saints they had to fight, even accounting for thousands of years of attrition.
There were also intact writings left in some of the waystations, shining a light on the distant past.
Sunny knew that the Underworld used to be the realm of Nether, the Demon of Choice, and that Nether had played a central role in the daemonic rebellion. However, what he did not know was just how important the Underworld had been for the uprising.
The Hollow Mountains, and therefore the Underworld, had been unique among all the realms. That was because they were connected to countless mortal realms, bridging the gap between them. Of course, very few were capable of crossing that bridge alive... unless the Prince of the Underworld welcomed them.
The Underworld had been the central stronghold of the Demon Legion. It was not only nearly impregnable, but also allowed the six rebellious Demons to swiftly deploy their troops to various mortal realms and move between them, attacking and retreating unpredictably, as well as recruit more warriors to the banner of rebellion. That was why the Demon Legion had been able to contend against the Divine Host in the early years of the war despite being a much smaller and weaker force.
But, as Sunny already knew, the Doom War had not been kind to the daemons. Despite their initial success, its tides eventually turned against them. As existence itself was coming undone in the annihilating flames of the bitter war between the gods and the daemon, the Demon Legion suffered defeat after defeat and was pushed back on all fronts.
That was why Nether and his siblings had made a choice to resort to one last, desperate measure — to open the Void Gate and unleash the Forgotten God upon the world.
In the last days of the war, the Underworld had become the last stronghold of the Demon Legion. The victorious Divine Host laid siege to it... but the daemons were preparing to launch a different, far more daring assault.
Descending to the darkest depths of the Underworld, Nether led their warriors into the Abyss and invaded the Shadow Realm, challenging Death and its endless legions — the shadows of everyone who had perished in the cataclysm of the Doom War.
