In the sky deep below the Lands of Ice, a white substance rises up from beneath the clouds, like some sort of secret fountain. It only ever appears in one place, making it even more difficult to understand.
Deep Snow is a discovery in Skies of Arcadia Legends. It is found beneath the Lands of Ice. The best way to find this is to head directly west from the Southern Cross, which is almost directly north of the Ruins of Ice. It is visible before discovered and is below the clouds, so the Purple Moon Crystal is required to find it.
