Lord Stoll was formerly the troll warlord leader, commanding an army for a long time. Stoll attempted to capture the gnome city of Mechastone so he could use its ore supplies. His invasion failed when a gnome attack distracted his guards long enough for Krunch to kill him. Although his second-in-command took over, his army was still wiped out by Cale'anon's band and the Gnomes.
