Point noted. Besides, if Lorkhan is dead, Talos is false, you are superior, you have better mages and you have more allies yet we are standing? That shows a weakness on your part. You have no proof Talos is false since that is just a belief. Talos IS true, as demonstrated by Martin Septim's genius by using the blood of Talos to enter Camoran's Paradise.
The Empire stands because it is allowed to stand. Just look at the Dunmer: had they worshipped as we worship, they would still be Altmer. But after a long series of betrayals and finally a curse by Azura...they are changed, their abhorrent Tribunal is dead, Vivec is in Mehrunes Dagon's Oblivion realm, and most of Morrowind is destroyed and controlled by Argonia.
Martin Septim could use the blood of Tiber Septim to open the gate to Gaiar Alata because as a Dragonborn, TIber had the blood of Akatosh within him.
