History of Caches of Echoes

Caches of Echoes: "Find all of the data caches in the Forest of Echoes." A Season of the Lost Shattered Realm triumph worth 2 points, part of the Shattered Scholar triumph for the Realmwalker seal.

How to complete

1. Have the Frequency Echoes / True Sight upgrade from the Wayfinder's Compass; caches only show with True Sight.
2. In the Forest of Echoes, align the first Beacon (cathedral ahead on the right).
3. In Memory: on a suspended island with a statue; activate the True Sight artifact in the starting area, the cache is opposite it.
4. Bearings: top of a tower reached via an Ascendant Anchor near the cathedral's left wall; keep True Sight up crossing floating slabs.
5. The Intruder: first floor of a building in a square full of Taken; follow the lanterns from the start and use a True Sight artifact.

A Bungie forum post reported the triumph bugging at one point.
