The Ascension Well represented an opening in the stone-covered landscape of the planet Ridlay. Every fifty years, during the planet's complete eclipses, entities that the inhabitants of Ridlay considered to be spirits emerged from this well. Consequently, the eclipse was a celebrated event, seen as a merging of the realms of the living and the dead, with the Ascension Well adorned with tributes to those who had passed away. However, during an eclipse occurring during the Clone Wars, these so-called ghosts launched an assault on Ridlay's residents, forcing them to abandon their settlements. Following the arrival of Jedi Master Mace Windu on Ridlay to look into the communication blackout, he journeyed to the Ascension Well accompanied by several clone troopers and a native guide named Agon. Windu concluded that the entities were living beings with troubled minds, and the party was then encountered by Count Dooku from the Confederacy of Independent Systems, who ascended from the Ascension Well atop a Multi-Troop Transport.
