Continuation of that Ram in the Vision ask. Now this being the first time I've watched Revelations since finding those info and theory posts about the Gods/Aspects of God. I find it very interesting that we did not see a Bat at any point during that vision. Makes me wonder, if we get future parts, if we'll see that vision again, this time starting at an earlier point and/or from a different perspective, to see how the Bat plays in.
I also thought that was weird. Especially since they gave Lyn a bat look as the sorceress, which said to me "Sorceress of Horokoth". But then the visions of the goddess(es) didn't feature a bat at all!
My current working theory is that Horokoth will not be a native goddess, but a deity foreign to Eternia. Horokoth, in the comics, was Hordak's patron deity and the goddess of the Horde, so maybe they'll introduce Horokoth when the Horde lands on Eternia in season 2.
Skeletor used to work for Hordak and maybe he at one time worshipped Horokoth, or maybe it just made that much of an impression on him that that's what his vision of a "goddess sorceress" is, and that's why when he made Evil-Lyn the Sorceress of Grayskull, he made her costume bat-like.
