dumb premise for a game - Medieval Aliens

[Shades of Eternity]

I've been on a "mocking ancient aliens" kick lately, so having a premise.

What if the Middle Ages in Europe were because of aliens?

I'll start
William the Conqueror was a hybrid.

I think this is a really fun idea. If you replace fairies or demons with aliens, it creates a fun twist on King Arthur and other medieval tales.

Merlin is a half-alien, the "lady in the lake" is a holographic projection from a crashed alien ship, Excalibur is a weapon built with alien tech.

For "magic" you could have alien nanotechnology that can be accessed and manipulated with specific alien words (which sound like magic spells).

Monsters could be alien species that escaped from crashed alien ships, or hybrids, or new creatures created by rogue nanotech!

and the nordic aliens are like ...right there.
