The ancient guardian is the Oldest guardian among all of the Guardians, dwelling within the ocean monument where the story of the Hidden Depths DLC unfolds. After the shattering of the orb of dominance, one of its shards landed within the hidden depths of a deep ocean. As the ancient guardian was guarding the monument it inevitably discovered the shard and became corrupted by it. With the addition of its newfound power, the ancient guardian got emboldened in expanding its territory. It began to spread its corruption to a nearby ravine, enraging the ocean currents. At the time that the heroes begin to descend the ocean depths, the corruption of the ancient guardian begins spreading throughout a coral reef known as Coral Rise, wreaking havoc on the nearby small islands. Upon reaching the end of the lower monument, the ancient guardian is seen destroying its own lair to challenge the heroes who entered the chamber. After an intense battle, they manage to defeat the ancient guardian, calming the ocean currents. More info: https://minecraft.fandom.com/wiki/Minecraft_Dungeons:Ancient_Guardian?so=search
