Old Kushim was called that, well, because he was old. He was the most ancient of the liches well before the war had even started. Considering the two-thousand years that had passed since then would put him somewhere around seven-thousand years old. With that amount of time, it was no wonder that he was also known as the most eccentric of the liches. He was known to go on long, nonsense filled rants, as well as burning down the occasional village in order to collect test subjects.
