What you see when you enter the Void.
The Void is the lair of The Reaper and is accessible only by Guardians. The void can be reached by either the teleporter in the Guardian Tower or by clicking the moon in Granemor. You are given four options: Battle, Guest, Go to Battleon, and Go to Granemor. Battle pits you against one of several Level 150 challenges (with one exception.) Guest will cause Death to join up as a temporary companion,unless he does notfeel like aiding you. The last two do exactly what they say: they transport you to their respective destinations.
