Yes, I did have a vision before the aborted mission. It was pretty much like what actually happened on the mission itself. But in the vision I just now had, it's true there were no shadow beings. Thank goodness. However, I think the explosion of fire could be just as fatal to us and to the people who live there, even if it doesn't destroy the planet itself.

[ Yep, the red sky mattered! It meant that the fiery event was not limited to just the swath of jungle that Curufin was standing in. ]
