The Seahills of the Snoutridge, colloquially known as the "Seahills", were the northernmost Common League region. Disconnected from mainland Commona by the Snoutridge Mountains and insulated by Wyrmhorn Gulf, they were historically a Human-majority land composed of small fishing and mining communities. Rivers, beaches, and coves were abundant as the hills reached the bay, but the flats were still arable enough to sustain agriculture.
Though the Seahills shared culture with Commona and paid dues as member of the League for protection, they still considered themselves semi-independent. Their communities were under constant threat, whether they be raiders from the mountains, pirates from the Siren's Isles, or armies from noble houses in . In times of need, they often relied on help from the from the Kingdom of the Twelve Mountains or the of Ardhon Miniel, as most Common forces were stationed on the other side of the mountain range.
