I love Harry Potter. I love the middle ages, so I made a rp board set in the Potter magical world in the year 1360 along with a friend. I also have a blog on tumblr with period faceclaims. You should check that out (and follow me).
My sets and collections generally reflect what I am currently doing rp-vise. Once there was current day Potter, then there was the Tortallan universe and now there is medieval Potter.
