wierd start

A seventeen year old boy named Adam was walking down the street when suddenly the strange glowing circle appeared under him. He lost control over his body and strange knowledge started to flow into his mind. A knowledge about ancient magic incredible technology and various universes, multiverses and omniverses, and how every story, every idea, even the weirdest exist somewhere, everything happened, will happen, and is happening at the same time. When the stream ended he got teleported into strange white room and heard a weird voice in his head

-General AI type A GAIA activated. New host found, initiating mind link.

Adam started to feel pain in his head when even more knowledge went into his already overfilled brain and then he fainted.

When Adam woke up he was lying in bed again

Where am I, he thought to himself

Suddenly he heard strange voice

-main bedroom sector 26

-who are you?

-GAIA AI managing that place.

-so where is this place - he asked

-currently in space between dimensions.

Suddenly he remembered the rest of information. Adam started checking the room. It was empty except for bed and a light on a celling.

After talking a bit with Gaia he found out what happened, Apparently he was chosen in great multidimensional lottery from all versions of himself to became new owner of that place with many entities that past owners enslaved made or just took there, because they could. The place itself was a giant fortress, filled with mix of magic and technology, older than time and space, built to protect and help the owner. Every owner got bored after some time, and because becoming an owner automatically gave you one of the strongest immortalities possible, or rather awakened it, all previous were sealed deep inside the complex. After that a new one would be chosen from infinite copies of the original, that existed in various timelines and universes.
