Leadership is determined normally for Necron fleets, except any ship with a Sepulchre (see below) automatically receives a leadership of 10. The fleet gets 1 re-roll and can purchase 1 extra for 25 points and a second extra for a further 50 points.

The Tombships in Necron fleets include a special vault called a Sepulchre. What exactly it is that rests inside this thrice-damned place is not known, other than that it exudes an aura of sheer visceral horror that radiates across enormous distances even in the vast emptiness of space. As well as being a resting place for whatever unnameable horror that lies inside, the Sepulchre contains technological wonders that are so advanced as to be magical to virtually any other race and project the will of the creature within far beyond the ship.

Only capital ships are large enough to contain a Sepulchre and only Tombships include one as a matter of course. The Scythe class Harvest ship can be optionally adapted to contain a Sepulchre. A Scythe adapted in this way is known as a Reaper. It will have 1 less Portal to make room for the Sepulchre but the Reaper can project a Nightmare field in the same manner as a Tombship.

Note that there is no requirement for a Necron fleet to include Sepulchres and it is actually quite normal for them to consist of unmodified Scythes supported by Jackals.
