When will the stars align in Elden Ring?

This question torments those players who prematurely reached the castle of the Red-Mane in the Starry Wastes. If you go there and are told that the festival will begin when the Stars align, you will have to perform a couple of additional steps.

First, head to the north of Lake Liurnia and look for a castle in the northwest corner, behind which there will be three towers. Kill the dragon, find Rennie in the middle tower and agree to serve her. You can now return to Red Mane Castle to find Blyde, the ghosts, and the herald in the square, who claims that the stars have aligned. Speak with him upstairs and head to the battlefield with Radan, Starbane.
