The Defender was a role in traditional challenge by personal combat in Guiteica.[1]
The challenge included two individual fighters attacking each other with dematoils. The Succession Judge was to be a neutral observer. Each fighter was allowed to have a Defender, traditionally used to avoid uninvited interruptions of the battle, but more commonly used to verify that the battle was kept honorably.[1]
