NICE SHACK!

That's one heck of a stronghold, "Katla!"

My OC Katla lives in a more Saxon/Viking style fort, part wooden part of stone (when not at EAH, in the East Wing dorms). Hers stands also on a cliff, overlooking a vast lake: the Vänern, in the Swedish province of Värmland. Though it's a more wooded area.
I have sailed on the Vänern myself, and I have seen a lot of olden-day mansions on its shores. Thence came the inspiration.
