2935 Host 4

From recovered information about them, their life under internment was uneventful, until they had Shifted into a world affected by The Reaper's Cave.

By the time they returned to their home world, whatever vector causes people who pass through The Reaper's Cave and "become death" in order to spread its effect had latched onto Grabnok, causing the death of their home universe in the blink of an eye.

It is not known how long it took Grabnok to connect the dots between the dead world they had Shifted into and the reality they are now in; nor how many universes they have doomed because of these two abilities that they cannot control.
