For a few years now, I've had this world grow in my head. Paleogena is a place where hundreds of prehistoric species that have since become extinct still live. Humans, or the proper term in my story is Velik Nos, since the ones that find their way there do not belong in the world we have and in the way that they are cannot be classified as 'human'.
As I was trying to say, there are Velik Nos that have made their way to the land of Paleogena and with them the dexterity to create complex objects. One kind that the native species found very important, were musical instruments.
