Trollheim's Grott is a black metal band from Finland. The band was formed in Kuopio, Finland, in 1997 by Troll N. Together with his brother Spellgoth they formed the concept of the Troll Syndicate, which are the main subjects of their lyrics, which often concern trolls wiping out or controlling humanity. Their first album was mainly symphonic black metal, although in their latest album they added industrial elements.
