Sanctuary Caches

Three Alien Caches serving as sanctuaries can be found located in a cave in the Deep Sparse Reef, right next to the Sea Treader's Path Wreck (Wreck 7), deep within a cave in the Northern Blood Kelp Zone, and inside an impact crater left behind by a meteor in the Dunes. These three Caches require Purple Tablets to gain access. Sanctuaries contain data hubs, atop which are Ion Cubes. These data hubs contain the backed up consciousnesses of several members of the Precursor Race. The Ion Cubes are purely ceremonial.

Deep Sparse Reef Sanctuary
Located within a small cave inside the Deep Sparse Reef, this Cache is sealed by a forcefield door that can only be opened with a Purple Tablet. At the far end of this Cache a data terminal can be found. Three data hubs can be found in both the left and right sides of the Cache, six Ion Cubes can be found on top of these.

Northern Blood Kelp Sanctuary
Located in a small cave, five hundred and sixty meters down in the Northern Blood Kelp Zone, this Cache is also sealed by a forcefield door that requires a Purple Tablet to open. This Cache features a data terminal in the center and four data hubs, two on either side of the terminal.

Dunes Sanctuary
This Cache is accessed through a meteor impact crater in the Dunes. The main chamber is reached through a long winded tunnel and is sealed by another forcefield door, which is also only accessed through a purple tablet. The tunnel continues into the main chamber, which contains four data hubs and one data terminal. Flora are also found scattered in the chamber, with occasional boulders on the ground and stalactites hanging from the ceiling. It is possible to take the Prawn Suit past the forcefield door, but the tunnel becomes too narrow to bring it any further; because of how long the tunnel is from the entrance, it is advised to leave a vehicle as close as possible for air resupply.
