d20 Future: CODEX GALACTICA
The Ancients known as the Protheans controlled a vast empire of worlds that stretched across much of worlds that are now part of the Galactic Concord over 30,000 years ago. They were are an amphibious humanoid species with empathic abilities. Much of their record keeping related to the creation of memory stones that they used to house their memories. Those that touch these items have their minds filled with images and sounds of the Protheans that used the stones before. However, few people are able to make sense of the images they are bombarded with, which can lead to sickness, insanity, and in some cases death due to severe brain hemorrhaging.
