Thanks for playing ponies! And OMG! You're the first (and likely only) person to recognize Eilean Donan!!! I don't know the castle personally, but I was looking up "Castles" on Wikipedia commons and that amazing photo came up! And now I know about it, such a romantic name for a castle. The original photo (linked on my itch page is "Eilean Donan at Dusk" by Syxaxis Photography)
