Ballistae were used during the second war. Ballista launch steel-tipped bolts to impale all in their path. As they require an awesome amount of force to be placed upon their tremendous bowstrings, these machines of war are reinforced with lumber from the precious ironwood trees. The ballista, a product of human design and elven craftsmanship, is a symbol of the unity between all those who have allied themselves against the Horde.
