For some reason the spaces appear in the editor, but not in the published post, so the “down” lines are in the wrong place. The join should be on the fifth letter of the “across” word, not the first

If I have the misalignment figured correctly then I think I have the puzzle solution.

Down = Ungoliant
Across = Shelob
