You might also want to put in there that the gem seed and Hero's staff were formed from a small portion of the star seed, the element that created the big bag. It reinforces how powerful the gem seed is and working with Light Hope from the book of living spells this was how the Gem Seed was able to begin the rebirth of Etheria.
This also gives new meaning to the reasion why Light Hope said in the Filmation episode "Welcome She-Ra long have I awated your comming". The moment She-Ra enteres the crystal castle with the sword of protection both haves of the gem seed come into contact again as the other half of the gem seed still resides in the crystal castle.
It would have been intresting to know if the star sisters would have been worked into the crystal castle lore, with the crystal caverns being just below it on sky dancer?
