Origin

The S.E.P. (ShadowGem Experimentation Program) is a organisation set to experiment on the ShadowGems. They are the reason that Shade exists.  The leader Nexun or Nex who's been controlling S.E.P after the original leader died. Before Nex the S.E.P was made to try and cure diseases, but after the original leader died mysteriously (Nex killed him to gain control), Nex became the leader, and is now using the facility to harness the power of the Nega ShadowGem so he can become the "Savior" of the world by becoming (in his own view) a "god". When they found out about one of their test subjects (Vane) escaping, they hired a assassin who goes by the title Falcon-I to kill Vane and gain the ShadowGem he's protecting, but after the truth is revealed about Nex being the one who killed his family, he's been set out for revenge. In Legends Unleashed 3: Dawn Of Dusk, they quit there experiments on the ShadowGems, instead soughting after the LuminoGem, A purified variant of a ShadowGem that was created after Heric's shift in alignment in Legends Unleashed 2: Rise Of Corruption..
