Hey guys,
I know this factions is already prety much done, but I visited the battlefield of Harlaw last week where one of the biggest battles between the Lordship of the Isles and the Kingdom of Scotland occured in 1411. A memorial was built there with the inisignia of both sides, one of them very similar to the badge you chose for the LotI on WotW, so I thought I'd share some pics. Have fun
