@Seraph: My idea at the times was that each of the four kings (ie one king for earth ponies, pegasi, unicorns and sea ponies) would each get at least one weapon and one 'lesser' artifact. Like, The trident was the sea pony weapon and the goblet was their lesser artifact. The staff of Starswirl was the unicorn weapon and the Crown was their lesser artifact. Each of them in the original thought would also have a special region - like the Cove of candles was my idea for the sea pony region, the mountain in the yeti's curse the pegasi's, the garden's of equestria's the earth pony's, etc. Trick is I don't know
exactly what the artifacts are, so I can't peg them all.
@Red: Possible... but to be honest I don't want to push for anything too solid, in part because I'm taking really heavily from
The Colour You Bleed canon for it. The four Kings would relate
really heavily to an idea I had for a possible overarching plot, Blueblood would have to go all over the continent (and even outside of it, to places where the world basically went non-euclidian as a result of an ancient magical war) picking up a representative of each race to sort of replace the original four kings and go up against an old god - as in, a Discord style creature that was responsible to creating one of the elements of reality. Possibly time, but might be something else. SO I kinda don't want to feel like I'm pushing the four kings angle
too hard, even though it wouldn't be directly related to that.
