Traitor victory The would-be “Meduson” turns out to be Alpharius; the survivors from the “Sisypheum” are pawns in his purge.

A group of survivors from the “Sisypheum” joined “Shadrak Meduson” in order to kill Alpharius — but “Meduson” was Alpharius himself, who had dressed his own in Iron Hands armour, and the loyalists became pawns in his scheme to purge members of his own Alpha Legion who inclined to loyalism. Nykona Sharrowkyn struck down the skilled Alpha Legionary Ashur Maesan.
