*Almalexia/Boethiah is the Rebel to Molag Bal's Ruling King, with Mannimarco as the witness/architect (i.e. Magnus) and Abnar Tharn as the Tsunimac (?)
*The Soulburst was probably a Dragon Break that caused the firmament to go screwy; the Planemeld is the Dawn that occurs between the Middle Dawn and the Mythic Dawn
*Ayrenn and Emeric would be Rebels but they're to busy trying to kill each other to see the true Ruling King
*The player characters respawn because they became unmortal pseudo-daedra spirits like Camoran's ascended immortals and Sovngarde heroes
*If this conflict drags out all through the Imperial Interregnum, then Hjalti may have been created by the Minute Menders as part of a quick fix solution
Does that sound about right?
