B-Stl

In Metroid Prime 2: Echoes, B-Stl was one of the 10 Keybearers. 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 Dark Torvus.
