Sedh

Sedh is a frozen, polluted Necron frontier world of the Ithakas Dynasty, the exile dump where disgraced dynasts were sent to rot under Lord Oltyx. This Ultima pin is that Twice-Dead King rock, not an Imperial agri-world with a similar hiss.

Oltyx killed an Ork warboss here before anyone admitted the greenskins were fleeing an Imperial crusade. The garrison evacuated toward crownworld Antikef, leaving Sedh as a ruined freezer full of failed nobles and leftover spore. It is not Ithaka the Iron Snakes homeworld.

Sedh still matters as Oltyx's disgrace posting. Unofficial summaries keep the Ultima parent and refuse to file this row under Iron Snakes Ithaka or as the Ithakas throneworld Antikef.
