Well, I found a new best mate. The little fuzzball isn't exactly what I meant, but I'll take her.
I've dubbed her species Renopila Amplexus. They're small, cuddly little herbivores, and as far as I can tell, taming one has no practical use. I just couldn't let the her starve to death, though. I guess all this rubbish with golems and wyverns has quelched what was left of my scientific instinct to leave nature to nature.
At least we provide each other with a little warmth at night, and her antics have helped to keep my spirits up. I suppose I'll need to give her a name.
