Brell Sediment is a codex entry located within the locations section of a player's codex once it has been unlocked. It can be earned on the planet Taris, and provides a brief background and summary of the area known as the Brell Sediment.
|“||The Brell Sediment refers to a large area of Tarisian ruins dominated by a massive acidic lake and a former chemical plant. It gets its name-somewhat ironically-from Ark Brell, a leading environmentalist on Taris in the days before its destruction. Before the bombardment, Ark Brell set up several water purification and waste disposal plants on Taris, with the aim of turning the waste from Taris's factories into alternative fuel sources and minimizing the waste produced by the massive city-world.
