We take a peek at The Kalevala, a work synthesized from the oral folk tales of Finland, a work that inspired Tolkien so much that he copied it unreservedly, a work that merits countless appositions.
Also, a work that is excellent source material for pet names. Characters like "the Gap-toothed Hag of the North" and "Steady Old Väinämöinen, the Everlasting Wise Man" can easily be converted into names befitting the pets' traits: "the Gap-toothed Ciup of the North" or "Steady Old Bobertcita, The Everlasting Wise Cat".
