Ten years after ME3(2197) a small team of Doctors, Scientists, and Xenobiologists are dispatched to an uncharted planet to study the remains of an ancient civilisation and partially mummified remains. However, their prodding awakens something ancient and primal, and they must fight to survive against this unknown threat. All characters are to be Scientists, Mechanics, or Doctors. The majority of the security forces are to be controlled by the DM, other than maybe one or two OC's that fit. No Commander Shepards here.
No military characters will be made active until a later part of the narrative, where these characters (if any are created) will lead the rescue effort. Characters can be made at any point in the narrative, but their introduction must make sense.
