Add a new rule named “Dimensional Travel” and give it this text:

Each Necromancer has a publicly-tracked Dimension, defaulting to The Void, and a number called Power defaulting to 10.

{| class="wikitable"
|+ Dimensions
|-
! Dimension !! Effects
|-
| Material Plane || If it is on or after January 11 2024, your Dimension is set to The Void.
|-
| The Underworld || Hourglass Action: Gain 1 Power.
|-
| The Void || Hourglass Action: Lose 1 Power, to a minimum of 0. You cannot use Necrotic Redirection or Planar Portal to change your Dimension.
|}

The Effects of a Dimension only apply to a Necromancer if they have that Dimension.

If it is on or after January 12 2024, any Necromancer or the Grim Reaper may remove Material Plane from the table of Dimensions and then remove this sentence.

In the rule “Knowledge”, add the following to the Ultimate Truths table:

|-
| Necrotic Redirection || 2 || Choose a type from your Cohort of Skeletons, Zombies, or Ghouls, where you have at least 3 of that type and privately communicate to the Grim Reaper that you want to use this Knowledge, your choice of Cohort type, and a Dimension you wish to travel to.
|-
| Planar Portal || 2 || If you have at least 15 Mana and your Dimension is not Material Plane or your Location is the Ancient Portal, privately communicate to the Grim Reaper that you want to use this Knowledge and a Dimension you wish to travel to.

In the subrule “Locations”, add the following to the Locations table:

|-
| Ancient Portal || You may use the Planar Portal Ultimate Truth || 1 || Ruined Castle
|-
| Another Dimension || - || 0 || The Planes

In the subrule “The Hourglass”, replace the text “described in the Effects of their Location to that Necromancer” with

that applies to that Necromancer

and in the same subrule, after the bullet that begins with “If the Necromancer wanted to Possess a Corpse”, add the following bullet points:

** If the Necromancer wanted to use Necrotic Redirection, subtract 3 from their chosen Cohort type, set their chosen Dimension, and set their Location to Another Dimension unless the chosen Dimension is Material Plane, in which case set their Location to Tower.
** If the Necromancer wanted to use Planar Portal, subtract 15 from their Mana, set their chosen Dimension, and set their Location to Another Dimension unless the chosen Dimension is Material Plane, in which case set their Location to Tower.

Set each Necromancer’s Dimension to Material Plane.
