When I got to the end of painting my Numidians, I found I had one body left over. I say "body" because it was lacking both a head (transplanted onto a late Roman archer) and a right arm. However, I had plenty of spare arms and heads from the Victrix plastics set of Numidian infantry. A little surgery gave me a rider with a raised sword and a helmet.
I then needed a horse. None were immediately forthcoming but then I happened upon a 25mm scale unicorn in my box-of-things-that-might-be-useful-for-Glorantha-one-day. Yet more surgery, this time of a veterinary flavour, produced a suitable mount.
Married together with a little Green Stuff and superglue we end up with this chap:
I've called him Arabio after the last of the Numidian kings. I figure he can serve as a commander of light horse in future games of To The Strongest!
