Thunder Guard is a realm within a Belegarth; A full-contact, live-action combat game in which combatants engage each other in battle with foam-padded boffer weapons. Unlike similar medieval combat games, Belegarth allows for grappling, hard hits, shield bashing and shield kicking. Additionally, Belegarth is purely combat oriented; The roleplaying aspect is limited and there is no use of 'magic' during Belegarth battles.

Belegarth realms are spread throughout the United States and the game is becoming increasingly popular in Canada.

Thunder Guard was founded in 2006 and was the first Canadian Belegarth Realm.
