The Keeper's Insights for Episode 3 are pretty much the easiest. The locations are on the edge of the map and the room is always the same room with the same location inside.
The '
Insight of War' required Knowledge Sequence 1, so do as first
Insight of the Titan and
Insight of Blessings include Isu Data Cache and Isu Codex in the locations and you should have enough "Knowledge" for the '
Insight of War' location.
My video shows also the Isu Data Cache, Isu Codex and the chests in the specific locations.
