Regarding Bard's Lore

I think it is far more likely Soraka was comparable to Bard before she sacrificed her divinity; they were aware of each other's existence and served differing roles. Bard seems to be focussed on preservation as a wandering custodian of the world, while Soraka is based more on restoration, such as returning what was lost as best she can, i.e. healing, therapy, and so on.

Also, they are both extra-dimensional beings that manipulate the cosmic forces of reality, not to mention they both have horns.
