"Sealing the portal is one method. Even though we don't know why the portal appeared in the first place, it was undisturbed for thousands of years prior. After sealing it, it should remain undisturbed for another several thousand years. But this is only an estimate, the portal could reappear in decades or centuries.

Furthermore, we may have to face an even older, undead being created from the corpse of a First Epoch creature that has been tainted with divinity, and ultimately, a newborn god of death?"
