Xykon character analysis

[Winter]

I think we're forgetting something important: Serini's diary. Xykon knows EXACTLY where the gate is.

That depends. The exact meaning of "exactly" is also important depending on what you mean Xykon does?

And yes, if he comes, he'll go right there. He still has to go there, though. Teleport right at it is probably not going to work, he'll have to walk/fly to the coordinates in the desert just as anyone else and then has to make his way to the gate (around which Girard might have build something, rocks, the pyramid etc).
