I'm still of the idea that Elidubus has a part of Zodiark in himself, or he's like a fragment of zodiark, but we'll see.
If Minfilia and Zodiark are the same and Minfilia allegedly has a deep connection to Hydaelyn I think we can assume that Elidubus has the same connection.
Both probably are a vessel in the end





and both shall submit to our Divine rule. For the only one suited to rule...is US!
