History of Grimoire: Allies—Eliksni

Overview

Grimoire: Allies—Eliksni is a Triumph in Destiny 2 in the Grimoire series. It is tied to a Grimoire card about the Eliksni, the Fallen faction.

How to complete

Grimoire cards are kept in the Hall of Champions, which opens from the Destination tab. To get there, finish the opening cutscene and the short Tower mission where Lord Shaxx opens the door. Then open the Destination tab in the main menu, click the Into the Light logo on the left side of The Dreaming City, and select the Hall of Champions icon. Find the Eliksni card and interact with it to collect it, which completes this triumph.

Destinypedia describes the Hall of Champions in the past tense, so the card may no longer be obtainable.
