The Cambrian Explosion

Overview

The Cambrian Explosion is a lore-entry Triumph in Unveiling, the Shadowkeep book of messages about the Light and Darkness. Its narrator argues that predation drove the development of complex life on Earth. This is the narrator's ideological account, rather than a playable historical event.

Original acquisition

Unveiling entries were delivered through weekly visits to Eris Morn on the Moon after completing Beyond, the final Shadowkeep campaign mission. Continue that book's correspondence and claim unlocked lore records in the Triumphs menu. The title does not require explosive multikills or completing a combat challenge.
