The bloated corpse of a decaying gigantic creature is necromatically enhanced and fused with an undercarriage for use as a grisly and terrifying airship. The methane gas from tissue decay keeps it buoyant in atmosphere, but it can be even more flammable than hydrogen if it escapes...
Elven Light Horse - a lithe and small animal well suited to the forest home of the elves. It has semi-cloven hooves, a longer tail, like that common to unicorn illustrations, and always a snow white pelt. Lives inthe forest, able to stand on back legs to crop leaves from the lower branches of trees. Shy and easily frightened, but at peace when around elves.
