Brigandia

Brigandia (Briganteers in the Yen Press translation) is a guild known for looting and PKing unsuspecting players. It was led by Demiqas prior to its disbandment at the hands of Silver Sword. In the light novel, however, the guild still exists, as Demiqas is still listed as belonging to the guild.

Overview
Brigandia, after the Catastrophe, ruled Susukino with an iron fist, PKing anyone who dared leave the city, disagree with its members, or otherwise oppose their rule. Its members kidnapped both People of the Land and Adventurers, especially females, in order to sell them to slavery or rape them.

Serara was personally approached by Demiqas, who offered her to "simply" be his servant, but ended up catching him off-guard and running away, enraging him. Her rescue by Nyanta and plea for help to Maryelle led to Shiroe's Party travelling to her rescue. In the ensuing duel between the two groups, both Demiqas and Londark are soundly beaten and killed.

After the subsequent demoralization of its members, Brigandia slowly lost its hold on Susukino, with the city falling further into anarchy and chaos until Silver Sword, on its self-imposed exile from Akihabara, barricaded the city and took control. Brigandia dispersed soon after, with most of its members leaving the city for Minami, including Londark. However, some of its members still remain in the light novel, as Tetora mentions them being "envious" of Demiqas due to his marriage to Upashi.
