I'm almost positive that every song on Master of Puppets is in E Standard tuning, except "The thing that should not be". So, as far as I know Orion is in E.
everything is in standard, witht the exceptions of:

The thing that should not be,
Sad But True,
most of Load/ReLoad,
and St.Anger
Rojam's new and improved band!!!!

Listen a little bit, we DON'T suck!
