Fics like Birth of a Celestial Sanctuary

What if Rimuru Tempest was never a slime? What if, instead, the Voice of the World sent a celestial beast crashing into the Sealed Cave — ancient, luminous, and trailing flowers with every step? What if the first thing Veldora Tempest saw after three hundred years of isolation wasn't a small blue creature, but a falling star that walked through his prison and asked if he was lonely? What if he went by a different name? Everything is the same. Everything is different. And the sanctuary Ranmaru Tempest builds will shake the world to its foundation.
