I think its an interesting concept. I am somewhat interested but it would depend on the mechanics of it.
If they are going to be in different geographical locations around the country, then how are they going to interact?
Are the covens going to represent a certain type of magic? For example: Necromancy, Elemental, Divination. Where you have members of all 4 covens in one city?
For their to be drama and tension, they need to be physically close enough to interact. Will everyone be a witch or warlock? Does the general populace know magic exists or are they trying it to hide that from the normal folks without magic?
Do you seeing this being more nation versus nation type RP or individuals from rivals groups in one rp together?
