This is fun to theorise even though it is pure speculation until we get some more information from Brandon.
My other thought to try and connect them is the shards we know the associated numbers of. Presumably the shards under the same Dawnshard have a numeral connection eg: 1,2,3,4 or 4,8,12,16.
Can the ones we know or have an educated guess at the numbers be linked?: Preservation (16), Honor (10), Odium (9), Virtuosity (13?), Endowment (5?) maybe others I can’t think of right now.
