Sin Capital

Biodata

Background / History

Sin Capital is the largest criminal settlement on the Frontier Prison Star, inhabited by prisoners from across the galaxy. Its population treats lethal violence, gang conflict, and public combat as routine parts of life. 13 20 27

Jiang Xiao's announcement that he was coming to Sin Capital after escaping the Old Capital immediately unsettles smaller gangs while exciting prisoners eager for chaos. His reputation as the “Old Capital Killing God” becomes a major subject of citywide discussion before he even arrives. 13

By the time Jiang Xiao reaches the city, Sin Capital is locked in a long-running power struggle between the Sin City Council and the Black Mech Gang. The Council has numerical strength and affiliated gangs, while the Black Mech Gang controls extensive mechanical resources and technology. 18 20

Jiang Xiao's attacks on the Mech Martial Gang and later the Wicked Soul Market further destabilize the city. His victory over Gulab allows the Spark Gang to publicly claim influence at the market, challenging the existing balance of power. 27 37 39

The Council eventually declares total war on the Black Mech Gang, ordering every gang to choose a side and declaring that “there are no neutrals.” The conflict spreads through Sin Capital and the surrounding wilderness, displacing criminals and escalating into regional battles. 52 65

Governance and Factions

City Conditions

• Sin Capital is a largely lawless metropolis where gangs, escaped criminals, martial artists, Espers, and mechanized troops compete for territory and resources. 20 27
• Pan-Humans face systematic hostility, particularly from the Sin City Council, Viper Gang, and Blade Armor Gang. A Pan-Human martial artist cannot safely live openly in most alien-controlled areas. 18 20
• A gang possessing even one Tier 2 Elite is considered a major force within the city. 26
• The city’s culture rewards notoriety: prisoners react to Jiang Xiao’s challenge with excitement, betting, fear, and anticipation rather than expecting protection from authorities. 7 13
• The city's Sin Coin economy is heavily affected by faction warfare; the currency’s value plummets during the conflict between the Council and the Black Mech Gang. 67

Infrastructure and Commerce

• Entry has no formal conditions, but most shops and markets require gang identification or Sin City Council certification through network terminals. 20
• Sin Capital’s black markets and illicit businesses are closely tied to the Spark Gang, despite the group’s lack of formal recognition within the city. 20
• The city maintains an extensive network system used for news, discussion forums, battle broadcasts, gang intelligence, and live-streamed violence. 8 9 10 37
• Three orbital defense ships hang above the metropolis, serving as a constant reminder that the prisoners remain confined to the planet. Their weapon range limits how far the city’s factions can escalate their conflict. 20 65
• Kasar Street Block is a heavily defended Council-controlled district, protected by mechanized troops, detection systems, fixed defenses, and Electromagnetic Tanks. 22 23 43 45
• Wicked Soul Market becomes a major flashpoint after the Viper Gang takes control of it with Council backing. 35 36
