Death to the Ing, and to the dark world they dwell upon!

—Returning the Sky Temple Key

In Metroid Prime 2: Echoes, B-Stl was one of the 10 Keybearers and part of Cadre 1. Her body is found in the Main Reactor, which is odd because this is part of the Space Pirate mining facility, which was created during the war. She was the mate of J-Stl, another Keybearer. The similarity in names suggests that the Luminoth follow a matrimonial naming tradition similar to those found in many Earth cultures.

Before it was collected by Samus Aran, B-Stl's Sky Temple Key was located in the Dark Oasis area of the Dark Agon Wastes.

Logbook entry

I can go no further. Here in this reactor, I go to join my fallen mate, J-Stl, in final rest. Though I die with honor, a shame falls on my house until the key I seek reaches its destination. May my brothers find my burden, that the way to the Sky Temple will be opened at last.

Logbook entry

Gallant B-Stl. She lies deep in a fortress of dry land.


  • Oddly, B-Stl's body cannot be scanned before Samus obtains the Dark Beam; in fact there is no indication of her body's presence until after the beam has been obtained. This suggests that B-Stl may have still been alive before ultimately succumbing to any wounds she received in battle or being killed by the Ing.
  • Her name may be pronounced "Be still." This is also a line spoken by Zero Suit Samus in a victory message in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U.
