Death Crystal
They all cursed Eldrian and Ceph at the top of their lungs when they saw all the empty rooms. It didn't take long however for them to find rooms yet to be looted. So they quickly got to work and forgot about the two.
Eldrian and Ceph instead started trying to move deeper into the cave again. The array was slowly shutting down, but not completely. As such, they kept being the first ones to enter the new areas that were accessible.
Ignoring how frustrating this must be for everyone else, Eldrian just kept on pushing. Finally, two days later, they made it to the core.
By this time his inventory was overfull and he had to even abandon some of the weaker items he had on hand.
Stepping into what Eldrian assumed was some sort of lab/bedroom, Eldrian looked around with Ceph by his side. His eyes flew wide open when he saw two purple crystals reflecting the light of Fos.
