The Pyramidion is a Vex-themed strike from Destiny 2, first released with the base game in 2017 and set deep beneath the surface of Io. Guardians descend into the structure to stop the Vex from converting it into a world-ending weapon, and the approach is marked by the cold, humming ambience of the machine world. After Io was vaulted in 2020, the strike returned in a reworked form, keeping its identity alive. Fans of the series still pull its sounds for edits, streams and lore videos.
