According to rumors, Genshin Impact will be making the map of Teyvat whole again with Version 4.6, as it will feature the island town of Petrichor, Bayda Harbor, and the underwater ruins of Remuria. Though previous leaks have pointed towards Bayda Harbor and Petrichor as almost separate map expansions, it would appear that both claims may end up being correct. Genshin Impact has long teased this particular corner of Teyvat, and closing off the Fontaine update cycle with a zone featuring the ruins of a dead civilization is aptly fitting.
