The Blue Willow Basin/Valley is framed/surrounded by the The Hawktail Hills in Pelmon.
Characters coming of age in/from this locale will shape their perspective to the primary experience of Cultural Experience of the Riverdans.
The river valley once was a major tributary to the Nanford River, now its a fen ridden flood plain. The river is known as the Marshsail River – for the broken chunks of marshland that float down it.
Around the basin, and up into the hills that surround it, many trees grow. These include beech, birch, willow and others.
