I'm not sure why Thor told Durkon the Astral Fortress existed if Durkon would never need to know. Thor might as well have told Durkon that Redcloak had a niece. We the audience knew that. It adds nothing to the story if it is something the characters never need to know.
Xykon built the Astral Fortress to hide his phylactery, to keep it safe and so he can regenerate in safety if his body is destroyed.

But he does not have the real phylactery there. Redcloak has the real phylactery.

Therefore, why would anyone go there?
