The Tyfal River is a major river found in Estlan, on the continent of Impatria. It begins in the southern reaches of Spine of the North, flowing to the northeast until it reaches the Sjóhval Sea through Mitcur Cove.
The Tyfal is primarily know for the highly variable water levels, as some of its downstream regions shift dramatically with the tides. Further upstream, the river is much more peaceful. It is these upstream regions where Estlan's locals often stop to collect water, as the Tyfal sits in a relatively central location in the region.
