Funnel Webs- live in burrows jumping out on any that wander into their territory and steal their belongings. They dig systems of tunnels and excavate buried buildings to strip them of their assets.
Tech Junkies- resent the idea of having to lose technology only to rediscover it again in the future. They have almost a religious attitude towards preserving knowledge at all costs. Their aim is to find a way to use it to give them an advantage over the other tribes. They also trade information for food and medicines.
Harvesters- believe that the salvation of mankind is rooted in reestablishing law, order, morality and hence civilisation. They intend to rebuild society from scratch by rediscovering lost skills and crafts. They gather seeds, plant crops and live in civilised walled communities.
Sons of the New Dawn- are an arrogant and self absorbed religious order that believes that the apocalypse was brought about by God to cleanse the earth of sinners. They believe that they are the righteous and have inherited the Earth to convert nonbelievers and to destroy the unworthy.
