The world as most people know it is the tip of the iceberg.
In truth, there are hundreds if not thousands of worlds. In some of them, civilised life stretches out into the stars. In others, it barely leaves a single continent.
Sometimes, whatever mysterious force keeps the worlds apart...frays. Tears in space and time appear, joining two different worlds. Occasionally, inhabitants of one world stumble through into the other.
On a global scale, while undoubtedly life-changing for the unfortunate soul to travel between the worlds in such a manner, this has a generally minor effect. However, sometimes these Tears are more dangerous. Sometimes they happen to snatch up one fated to have a great impact on their world's timeline. Other times, they connect not to another world at all, but to a place of endless torment from which Demons crawl to threaten the inhabitants of the world.
It is to combat this threat that warriors - Guardians - are chosen, carefully selected from all the worlds, bestowed with a special weapon made of the fabric of the multiverse itself and tasked to travel between the worlds, sealing Tears and preventing Demonic influence from affecting their proper timeline.
You are one such Guardian, still a novice, soon to face the last trial before being recognised as a full member of the Guardians. But the Guardians are facing a Darkness the likes of which they have never seen before.
And perhaps a small group of novices will be all that stand between the multiverse and destruction.
Are you ready?
