It was in the module Perils on the Sea of Rhun under the description of DAELHAELIN CIRYA on page 10. In the same module it mentions a Staff of Flame and one other thing that I think I found in the Creatures and Treasures books I never found an entry for the Grey Robes of the Adept only this little blurb in this module. I'm not sure what +10 L/I is either. Thanks for any help on this.
