Skaakh
The lowest social group on Sin 4 [1]. The outcasts, the have nots and the sick. The Skaakh are hunted for meat, scavenge for food and recyclables, try to stay alive and out of sight as much as possible. They are of virtually all races, but none of the strong of good fighter species as they end up in the Arenas. There are Skaakh Slums almost everywhere but predominantly in the southern regions of the North Continent. There are hierarchies within the Skaakh society group. Skaakh usually band together some protection. Especially against the non sentient life forms that plaque the streets and sewers. The Skaakh sometimes find day labor doing the dirtiest and worst jobs for a few coppers or sometimes for a bit of food. Within the Skaakh, the sick and the maimed are the most shunned and usually don't last long. Another group that has it even worse are the Skaakh children, especially the ones abandoned.
[1] The Skaakh don't go underground as that is the region of the Nights and Sub-subs. The Skaakh who do are never seen again.
