Eromangus have eight sacks on their back. In days of old these sacks would have held vital nutrients, fluids and fats essential for their survival in the harsh Rovva moon wilderness.Nowadays the owners of the Rovva Hover Shop on nearby fetha use them to work in the maintenance section. They will spray paint, lubricate parts, fuel up engines and squirt sarsaparilla at parched mechanics. In return they are given nutrients, fluids and fats, which they can no longer store for long because their sacks are full of paint, oil, fuel and sarsaparilla!
