Exmortis

The Exmortis were a group of terrorists lead by Slenderman (who came over to this world from a parallel universe, left behind from Omegas rift) they had one goal - to spread the virus far and wide. The exmortis used the dead soldiers of the PK and the Rebels pumping them with the virus and implants using advanced machines.

The exmortis were a big threat, for both the PK and the rebels, and later created a nuke; threatening to destory the entire planet if they did not give them Claire (the sister) however the players refused and with Cara's help destoryed the nukes by setting them off directly onto the Exmortis base, destorying everyone inside.

The true goal of the exmortis remains unknown, but one common theory is Slenderman was trying to use the power of the Stone Of The Void to restore his home world, in a similar style to Kazimir Kral.
