So I went down into the midden and found the hand statue with the note and the key
The note says to get the five rings from the arcaneom
I cannot find it for the life of me.

someone help

It's the library with the Orc. Don't forget to take the key where you also found the note as the chest is a Master lock.

I know it's in the library
the library is the arcaneom
but where is it in the library?

Ok sorry, enter the library and take the left side. The chest is after the third bookcase.

you have to go into the library at night to see it

It's to the left of the librarian as you face him from the entry. Left of a bookcase and up against the wall on the floor. It's called the evidence chest, I think.

Its the big chest in the library, the only chest in the library, not hard to find.
