You left the teleporter stone on the ground before going to the easter egg area? If you have been to the castle but have not rescued Zandalor yet, your teleporter stones may be disabled (if an imp doesn't steal them).

You can get out of the easter egg area by;
Teleporting Anywhere, via hex editor

If the teleporter stones are supose to work, but do not, you can stick the one you have in a chest and and download another set;
Lost Items - guide and directory of inventory files
Then
a way out, if you're Stuck in the Easter Egg Area


The elf should be in the south west cell, IIRC, and there should be a guard by the stairs.
