Camp Averno can refer to three different things: the in-universe summer camp, the online event hosted by the team, and the real life gathering of assorted Averno musicians for recording (which often takes place at the same time as online Camp Averno but is otherwise unrelated).
Camp Averno is the summer camp hosted in the outskirts of Averno. It is also the meeting place of the Sprout Scouts, who have a long and loathed relationship with the campers. The Sprout Scouts have the camp buildings from September 1-June 1, when they have to vacate the premises so the campers can use them.
Online Camp Averno 2020
Camp Averno was held for the first time from July 27-August 29, 2020. In 2020, participants were sorted into cabins based on their departments: Cabin Solis was DHS and DCD, Cabin Noctis was DDL and DCM, and Cabin Terra was DLH and DHP); and students from DUE could choose their cabin.
Camp Averno's theme song, "Welcome to Camp Averno", was written by August Greenwood in the summer of 2020 and released on July 26, 2020.
Online Camp Averno 2021
The second session of Camp Averno was held from June 12-June 20, 2021. This year, instead of sorting campers into cabins based on their departments, the counselors made a quiz that people could use to sort themselves into cabins.
