Heracles -> Hercules

Eros -> Cupid

Proserpina -> Persephone

Medjay -> Magi

Djinn -> Jinn

Djedi -> Jedi

Djehuti -> Thoth

Why were these names changed?

Because they all point at esoteric truths and the "powers that be" in this world are making it harder for seekers to find answers by obfuscating links to those esoteric truths. Changing how words are spelled is a good way to do that.

Heracles and Eros are too close to Chi + Rho.

Proserpina is too clear of a reference to serpents.

The "dj" in Medjay, Djinn, Djedi, and Djehuti were too directly connected to the Egyptian asp hieroglyph.
