Wow! This bio is genius! The different He-Mans over 500 years addresses something that I've considered about how Grayskull had supposedly been undefended and didn't need to be defended until this current point in Eternia's history when Skeletor is out to get its secrets. I'm very much digging it and am looking forward to the explanation of how the Sword of Protection fits into all of this. Satisfactory indeed!
