I swear decoy, and rot go hand in hand with undeath. Though, it technically also goes with darkness. Have you considered a realm of an Abyss of eternal winter like hell? With ice and frost? Maybe even an ocean plane filled with horrors of the deep? Might keep things varied, up to you of course. I'm just throwing stuff out there. Anything could be given a paint of evil with the right amount of imagination.

Im avoiding connotations. Each plane corresponds specifically to one type of 'element' in order to allow for a diverse range of applications. Hence i'm dubious about adding 'ice' to the 'darkness' realm and so on and so forth. Still might add in some of those suggestions, however.
