Story: I am a evil necromancer Overlord who has many evil minions loyal to me. However a hero has greatly wounded me, and I have to go into deep sleep in order to heal and regain my dark energy. My minions remain loyal to me (no worries there) but I have to leave quickly before my enemies find me. How do I hide myself in such a manner that only my evil minions will able to find me? What is the best place to hide ? I don't want to leave some obvious clue that will get me ambushed by a bunch of annoying heroes.
Background: My world is like a magical-Earth, with the most common magic types being - elemental and necromancy. Spirits can be summoned, but they can't find people. I am a evil Overlord with 3 powerful minions (they are the most loyal) and a evil army. I have some time to prepare before going into hiding.
Question: Where is the best place I should hide ? Since I have some time (but not that much) to prepare before going into a deep sleep, it is possible to create artificial places with traps and all. But my evil minions have to be able to find me in order to awaken me at the appropriate time, when good is at its weakest etc. So the second question is, what clues (if any) do I leave behind ? I can't just tell my minions, "I'm going to this and this place" because it is possible to force clues out of them if they get captured. A subtle hint would be enough.
Note : For leaving behind clues, I can use code words, or hide in a place only my minions know about. Enemies cannot read minds , but they can get some clues (magically listening in etc)
