As it happens, I wrote a brief outline some months back for a year-long run. I think it fits the thread:
Well, I think the best place to start would be to keep it simple, and not lean TOO much on continuity. There's an old maxim (since forgotten by the Big Two) in comics that "every issue is someone's first", so I'd want the first arc to be somewhat "new reader friendly".
Arc One: The Man
It's been part of the mythos for some time that the Panther must periodically accept challenges for his mantle. This time around, one of the challengers is named Erik N'jadaka, the now-grown son of the late Killmonger. And, like his father before him, Erik wins the mantle of Panther, when T'Challa suddenly seems to lose his strength.
T'Challa undergoes a vision quest to discover why the Panther God has seemingly abandoned him, and along the way re-connects with the spirits of his forefathers, who introduce him to the TRUE nature of the Panther God (I never really liked the Bast thing).
Meanwhile, young N'Jadaka discovers that wanting to rule and actually being able to are two very different things. The tribal council may acknowledge him, but they do not respect him, as the representative of the Jabari (recently returned from apparent death at the hands of Morlun) leads a coalition against him. When TChalla returns, re-empowered and aware of the deception the youth played on him (a contact poison that blocked the Heart-Shaped Herb) , the young Killmonger is almost grateful, and swears fealty after his defeat.
Arc Two: The Nation.
T'Challa must broker peace with M'Baku and his coalition, before the country devolves to civil war. When M'Baku tries to get physical (his traditional fallback position), T'Challa slaps him down.
But that's nothing, compared to the verbal smackdown delivered by a suddenly arrived Ce'Athauna Davin, former Dora Milaje (and rightful queen of the Jabari) who had been away at university in the States. Her appearance was not just to help T'Challa, however, as she's brought ill tidings:
The Desturi are back. And they've brought an army, bearing black-market vibranium weaponry, derived from the work of one Ulysses Klaw.
Arc Three: The World.
Lines are drawn. Allies summoned on both sides. Battle is joined. And in the end, the Panther stands supreme.
