Eater of Worlds is a raid lair in the Leviathan raid - kind of like a smaller one within the original. Eater of Worlds is more fast-paced, but challenging as well, and requires an even more coordinated team of Guardians to clear. The main goal is to defeat Argos, the Vex Planetary Core responsible for Nessus's conversion.
Keep in mind that Eater of Worlds raid loot table is different from the classic Leviathan. Rewards include raid-exclusive armor sets for each class, new emblems, shaders, two unique weapons, and a chance to get the Telesto Exotic Fusion Rifle catalyst.
