Er Melina - Tumblr Posts
Out of all the theories I've seen on Melina's backstory, I'm suprised I haven't seen one saying that she's an offshoot of Marika like how millicent is an offshoot of Malenia. (Not saying it doesn't exist just saying I haven't seen it)
Like there are quite a few parallels,
Melina and millicent (and millicents sisters) wear similar outfits
We know that to become a God one has to shed parts of themselves (re. Miquela) and those parts can become living beings of their own (re. Malenia)
Melina has intimate knowledge of Marika (even words she said to Radagon in private re. The Melina dialog in the queen's bedchambers)
Melina is the only NPC that knows Marika's unique spell she made for the shaman village
Melina herself follows Marika's path in abandoning the Erdtree and the Greater Will (Marika shattering the ring and Melina burning the tree)
Heck there's probably even more but I can't think of anything else rn
