Just start concatenating words. If you like "Odin", but it's too common, just use something like "OdinFlow" which integrates something about its domain.

The actual full name doesn't matter that much, and it can still be called "Odin" as shorthand in the docs, but this way the full name can still have both the implications you want and uniqueness. Plus, adding "Flow" now makes it a tiny bit more self-describing than just a proper name.

A more obscure figure from the Germanic pantheon, perhaps?
