Does anyone know of a mod that provides such items?

Searching Celtic on the Nexus got some results you could peruse through to see if anything catches your eye: http://www.nexusmods.com/skyrim/mods/searchresults/? (just realized that doesn't work due to how the Nexus runs searches, but just enter 'celtic')

Ok. Thanks for that. I am presently on console (xbox) but have been thinking of getting the tes anthology for PC. I will be remaking my main character (Breton conjunction based mage) and starting from scratch and want to have it planned out.
