These are creatures from Advanced D&D, 2nd Edition, that I have converted to D&D Edition 3.5.
NOTE: The descriptive text for these conversions is still a work in progress. I hope to have those done soon so these creatures can be fully utilized.

The descriptive text has been completed for the following:
(From Greyhawk): Crypt Thing
(From Monstrous Compendium Volume II): Cyclops, Firbolg, Fomorian, Sandling, Verbeeg.
