I guess Earendil sounds a lot like Anduril - had to check and now I understand they are not defense contractors!

Got similar vibes from that name but because it sounds like a LOTR thing and that (sadly) makes me think Palantir.

Very much an LOTR thing.

Tolkien stole the name from an Anglo Saxon poem, with a somewhat unclear meaning. His version of the story is woven through lots of his work, from the very earliest days. You could view all of Middle-earth as elaborating on his attempt to assign a meaning to it.

I had to check as well. Their logos are also similar.
