Saga of Astral Mysteries (LOTMxASOIAF)

With the impending doom of my homeland, I was reincarnated into the Valyrian Freehold as the last remnant of the destroyed Household...
Yet there were several discrepancies that I found right away...
1st - There were Beyonders everywhere where one looked, Extraordinary Creautres and powerful men and women threatened the quiet life of my reincarnation and using my foreknowledge.
2nd - And this also meant that True Gods, Evil Gods, Great Old Ones and Outer Gods... and this was just the start.
3rd - The worst thing was that it was some sort of alternate world, and my foreknowledge became useless even faster than I could discover it properly.
But you know what?
I woke up to face the strings of mysteries and unprecedented challenges. The new Era was before us with the doom of the deceitful glory!
Witness the discovery of a realm filled with Magic, Machinery, Hextech, Beyonders and Gods... From the distant shores of Westerlands to the Realms of the Deep Ones, from the high peaks of Valoran to the dunes of Shurima.
