What I think the next champion should be, based on interesting lore

There are two specific entities from the lore that I would really like to see in game:

the Baccai, who according to loading screen tips are the deformed product of failed Ascension rituals

and

the Demacian dragon riders that Galio's design is based on according to his Champion Insights page

I previously suggested that the dragon riders be incorporated into Mordekaiser's ultimate, but that thread didn't get any attention.
