The freshwater undine prefers lakes and slow moving rivers, but can still be found in deep streams and waterways across the country.
Whilst the undine is often assumed to be a smaller, feral relation to the mermaid; this is not the case. Undine are closer to fish than men, and have all the intelligence of your average minnow.
They are solitary creatures and highly territorial, tearing at their prey with needle sharp teeth- and will have a go at an unfortunate fisherman, should they mistakenly catch one.
Wading barefoot in known undine territory is not advised.
