Before the first footstep
New worlds begin at a temple made from the same persistent blocks as the rest of the world. Its blessed wing faces its corrupted wing across a central crystal idol. Aurelia and Malachar are already there when your traveler materializes; the introduction waits for that arrival to finish.
Read the crystal
Stand within reach of the idol and use the contextual interaction. Reading it records an innate power grade once for that traveler. It is not a choice of morality, an item reward, or an invitation to reroll by reloading or changing worlds.
Old worlds remain yours
The temple is generated for new worlds. Existing terrain is not overwritten to make space for it. Your placed Hearth, not the origin temple, becomes your respawn anchor.
