Considering how old he must be and the fact that in one screenshot he says "And the world will see.", it leads me to believe that maaaaayyyyyybee he knows something about the Landfall. Afterall, Solstheim seems to be a place of prophecy, since the Oblivion Crisis was predicted by Oddfrid White-Lip in Bloodmoon

I highly doubt the Landfall will be referenced at all in Dragonborn...

Maybe not directly, in MK style, but at least a hint
