Only a few hundreds of years ago, there was the great war known as the 'Fallout' war, for many of the things that were to be created or used during this war, would wreak destruction on a scale that it would affect the world lastingly.
Two factions of this war were known to the general public, the intelligent tool troops of the Io technocracy to the east and the mighty magic users hailing from the centralist Sumari archipelago to the west.
But there was another, a third faction: The Sentinels. A mysterious group of people that have no known government, always disappear in the annals of history even after fulfilling the greatest of prophecies or slaying the greatest of beasts and have neither home nor family.
Those sages of us that know of them can only riddle about their true existence. Are they shape shifting Dragons trying to protect us as well as the world? Are they descended heavenly beings to right what went wrong or are they simply adventurers travelling through different planes of existence to find their biggest adventures yet? Maybe all three or none at all?
The only thing for certain is that without those sentinels appearing during the war, the war would have destroyed all life on our world.
Even now, remnants of this war still threaten our world:
Hibernating, self-repairing mechanical monstrosities hiding away in yet not rediscovered underground cities.
However, Io was not the only side of the war that would leave behind sins that could not easily be purged:
Sumari's rulers, the Circle of Sages had sagecrafted the strongest spellscrolls in all of history - The Fallout Scrolls
Each of them powerful enough to lay waste to a large part of our world, if not its entirety. Each soulbound to one of the sages. The scrolls are shielded by the strongest wards ever conceived. For all intends and purposes, indestructible. The sages themselves, immortal until the spell of the scroll is cast.
Even to this day, they guard their scrolls, but an unenlightened soul can't sustain time itself forever, it needs the sleep of death to recover. Without this sleep, the mind is put under eternal trials.
If only one of them would fall prey to the allure of casting their scroll to kill themselves, the dream of our world, of peace and prosperity, would be put to rest as well.
It appeared to be just a question of time until our world would be destroyed.
At least, until now.
