As the march of the metal semi-spheres commenced, the army of Lanthanor on the border wall were busily bustling around while fussing on contraptions placed at equal intervals which were all pointing forward.
This contraption was triangular, with a 5-foot long gleaming arrow in the middle which was being slowly pulled back on the string that was getting increasingly taut with each revolution of the handle on the side.
Indeed, this was a construct much like the ballista from earth.
Each arrow had a hole in the end, through which a wooden block was inserted that served to pull it back.
After reaching the desired position, the block would disappear into the groove on the ballista, shooting the arrow forward with explosive force.
Traditionally in Angaria, ballistae were used because of their specialty in assaulting barriers.
