Sedna Campaign

Space Marines Portal

The Sedna Campaign was a battle of the Great Crusade.

History

Fought in 803.M30, the campaign was the last battle to liberate the whole Sol System. Eight full Space Marine Legions were deployed against the Xenos "false world" of Sedna. The aliens were expunged by unknown psychic means using the powers of the Warp. In the aftermath, Sedna fell into silence and has since been lost by the Imperium.^[1]

Though the Imperium subsequently destroyed all records of Sedna's Xenos, at least one "artefact" of the Sedna Campaign was preserved but sealed away in Vault Tharsis Deca-Nine on Mars.^[2]
