okay, this got moved here. Deep breaths, people.
1. The Interregnum is not really the total blank slate ZO is interpreting it as, but there were almost certainly dozens of pretender kings sitting on white-gold's throne. You don't think Cuhlecain styled himself as emperor before that tricky nightblade let his men into Sancre Tor?
2. Ayrenn is a genuinely terrible idea for a character. ( not because she's an Altmer who isn't terrible person, but because she's a young ruler even by human standards. She could potentially have advisers a hundred times her age.)
3. Neither of these things matter because canon is a useless term in a world where people can breathe retroactive climate change.
