[Squirrelloid]

For more information about the Kingdom of Angmar, its probably somewhere in the 12 books of notes Christopher Tolkien organized and published, somewhere I haven't read yet. (its a lot of books, and they aren't small).

Some specific notes:

Uruk-hai are created by Saruman, and as such didn't exist in the time of the Kingdom of Angmar.

I have no idea if Orog-hai existed yet or not. There's a little reason to believe they were trolls resistant to sunlight.

Saruman should not be 'old'. He took the form of an old man, but he was a Maiar, and as such ageless and older than the world.
