I have been thinking about this mod recently and why not just by the way add some new things I want added to this mod.
Elephants (not Mûmakil) - Large peaceful beasts that drop Ivory when killed and can be sold to the Haradrim. Can be ridden
Toucans- Similar to the parrot and can drop feathers.
Hyenas- Cowardly animals that hunt small animals and runs away when approached
Ostrich- Proud animals that have a superb speed and drops feathers with killed. Can be ridden
Desert mouse- a mouse that have small holes in the desert.
The Scorpion worshippers of Wardith
Savage tribes of Scorpion Worshippers dwelling in their tree forts of the Far Harad Forest. Fierce warriors in the service of the One eye, riding Jungle scorpions to the destruction of the Taurethrim tribes. Poisonous scorpion stingers and claws they use with the normal weapons, they control the Far Harad forest. The forest men and all of Middle-Earth shall be poisoned by the Great Scorpion!
The items for the Wardith (Pickaxe, Spear, sword, Banner e.t.c ..... )
Wains: Large carts used for transporting goods and Soldiers.
Ivory: Drops from elephants. Bought by the Harad for great prices.
These are just suggestions but I would love to see some of them added!
