What was so special about this plane and how it was connected was all too obvious to Sylas. There were no real beasts on that plane, at least not in the same way Sylas was used to seeing them.
They were Spirits, beings without true physical form. And yet, they were little different from so-called "real beasts" nonetheless.
It was impossible for even Sylas to deduce the entire story, but if he had to guess, the original Mirror Dungeon was found in this plane by the original Ancestor of the Spirit Beasts. Thanks to this, they were able to slowly grow their power.
Under a series of coincidences and lucky chances, they were able to use a reward for claiming the first original Mirror Dungeon to incorporate a Spirit within themselves and thus become the first true Spirit Beast.
Slowly, over time, the Spirit Beasts grew into an enormous Clan with many dozen Spirits and Lineages divided between them all. But it all started right here.
