We are all working hard so that no matter where you are, and come heck or highwater (or cataclysmic explosion), you will always have the Superman Encyclopedia with you! The Supermanica project is our attempt to recreate and expand on the work of Michael L. Fleisher.
I just updated the Krypton entry with the moon details. Wegthor (or Weg-Thor) is not in Fleisher's original book, but I'm sure it was mentioned by name pre-Crisis.
