Woah - wait a minute folks - how does anything get to Aetherius?

It seems that the position of the mer is that the Gods and Daedra Princes all want to get back there but cannot ... how can mere mortals achieve this?

There is a fair bit of Lore on this matter what with talk of astronaughts getting there and Magnus creating the sun - it may be that I have missed something here in that I assume Aetherius is the Void or part thereof

does someone have a clear idea re this? pls correct me
