This is (another!!) one of Drew Devault's projects.
Like harelang, it would be a gigantic simplification of existing software.
And yes, it is written in harelang.
It was originally a test to see whether harelang could be used for OS development. (It can.)
Bruh I don't mean to knock on the project but the naming scheme seems like a CS undergrad took a mythology class. Makes me think of college hackathons.
