The Accursed Lake is a room in the Sky Temple Grounds. It appears in Metroid Prime 2: Echoes. Most of this room is covered in Dark Water, one of only four such rooms outside of the Dark Torvus Bog (the other three being Feeding Pit, Double Path and to a lesser extent Dark Oasis of Dark Agon Wastes). One Light Beacon and one platform on the water are present in the room. Several Dormant Ingclaws can also be seen. A Flying Ing Cache and its associated Sky Temple Key, the Key of J-Fme, are present in this room.

The Aether version of this room is the Industrial Site.

  • If one looks closely behind the mass of Dormant Ingclaws blocking access to the already inaccessible Dark Splinter Hive area, there will be a wall of Mutated Ingworms covered over the tunnel entrance (and covering an otherwise Empty Door). This wall of Mutated Ingworms is unscannable.
