Leaked footage from Genshin Impact 5.3 has been shared and the video seems to confirm a highly rumored character death near the end of the Archon Quests added with the patch. Version 5.3 should add the final main Natlan story missions, concluding the arc set in the Nation of Pyro and the region’s efforts to fend off the Abyss’ invasion. That has been achieved to some degree of success with the past quests, but the solution may arise with the update, which should also add several new characters to the game, including the Pyro Traveler and Mavuika in Genshin Impact.
