Irsle is a fair-sized island, able to hold as few as two packs with large amounts of territory and as many as five packs with small amounts of territory. Irlse's territory is covered with trees, and it's hard to tell where the water is until you walk in! It's separated from Nerair by the thin Rosthe Strait, and its only waters are from the Shrosthrin Sea. The only nearby island other than Nerair is Northir.
