Report: STEPS-RETRACED is one of the Hidden Report quests of The Witch Queen (Season of the Risen, Season 16). The Hidden post new intel on the Evidence Board in the Enclave on Mars, and Guardians investigate it in Savathûn's Throne World while Immaru, Savathûn's Ghost, and the Lucent Brood hunt for Osmic Fragments. It takes roughly 15 to 30 minutes. It requires Report: RESONANCE-COMP plus access to the weekly Witch Queen campaign missions (the Destiny 2 Wiki mentions Rank 13 with Fynch).
