1. How does Fate's cycle of Lightborn-Shadow God fit within the grand scope Cleansing cycle introduced in Enderal? Because, in Enderal, only the raise of the Lightborn is mentioned as one stage of the cycle. It being a cycle within itself wasn't mentioned, and it is kinda implied in Nehrim that the current Lightborn are not the first mages to declare themselves gods, nor would they be the last if the protagonist and Arkt hadn't interfered. My best guess? It simply wasn't mentioned in Enderal. If I had to theorize more, I think the defeat of Fate's personification, slain by two Shadow Gods, happens in each Cleansing cycle. The book "The First War, for the Creator" kinda implies the Eliath made Sarantha into Fate's personification for this Cycle.
This makes me think Sarantha, and any Personification of Fate chosen each Cycle, is just a piece in the game board too, as are the High Ones (as said by the Veiled Woman). If you guys (SureAI devs) ever get to continue with the series in TES VI, I'd be pretty excited to see who are the ones moving the pieces, the players, so to speak.
2. What does Arkt mean when he says he is the "Shadow God of his world"? Does Arkt come from a destroyed world in the Shadow World, those "destroyed by imbalance"? Because, as the Lightborn cause an imbalance that would have destroyed Vyn eventually, so does the Shadow God. With the help of another one, Arkt killed Fate's Envoy (not the personication of Fate) sent to kill him, so he temporally freed himself from death. Or maybe he is from Vyn, awaiting an Envoy of Fate to kill him. But then, with a Shadow God alive, the new Lightborn cannot rise. I don't know, I am pretty confused by this one. And how it mixes with Vyn's Predestination, I simply don't know.
Those are the first questions coming to my mind for the moment. If you'd care to answer, thank you!
