Backgrounds represent part of the history of a character in the larger world. This will not have any mechanical effect but will help more in creating NPCs as part of a character's history.
Backgrounds
Abiogenic
Abiogenics are those who were created spontaneously from the digital world and their descendants. While they were always present there was a massive boom in population after the portals were opened.
Bound
The Bound is a collective term for the sentient beings that were trapped in the digital world after the portals. The term itself is something of a comprise describing their present condition more than any sort of identity.
Delvers
Delvers are people from the physical world who are stuck in the digital one. They might have been playing a game, streaming, or just general internet surfing and woke up to find themselves in the digital world. Even after the original event people still pop up usually willingly. However, it isn't unheard of for governments to disappear people by sending them digital as it is a one-way trip.
Interfaces
Interfaces were programs created to interface with the digital world before the portals opened. Before the ritual, they were more or less glorified drones or script bots that would collect as much data as possible (usually for corporations). After the ritual they all became sentient beings. Much to the dismay of the corps any attempts to recreate said programs also result in sentient beings who more often than not lack any special loyalty to their creators.
