Xiphone
Popularized around a decade prior to the start of the game, Xiphones are personal information terminals that, like smartphones, also have communication capabilities. They’re additionally capable of tapping into social networks and have games, which have made them hugely ubiquitous. Perhaps most importantly of all, they can provide synchronized verification of their owner’s physiological data, which can be used across a variety of services and security systems that are in development in the game’s world. Unlike real smartphones, though, they have a mysterious gear below the screen that makes them stand out.
Soul Devices
Special armaments that those with ties to the Other World can manifest. Possessing myriad possible forms, no two Soul Devices are alike. Specially made up of spirit particles and materials from the Other World, it’s effective at dealing damage to the Greed, as normal physical attacks otherwise do little to them.
Nemesis
A mysterious organization with agents of unusual talent. They do extensive behind the scenes work as “management for the Other World” and have amassed a broad network of magic users, spirit power users, and wizard tool artisans. Supposedly there is one headquarters in the UK and another in the US, but no one knows for sure. In the event that the Other World aptitude is detected, a person can begin training in earnest if they wish, and after learning how to use Soul Devices and studying up on the Other World and Greed, an agent can work all over the world.
