Flamepunk: Flamerunning

The Realm of Flames, also known as Flamespace

'Runners access it through rune emblazoned obsidian obelisks, hence the network of information stored there is often referred to as the Obsidian.

The spirits of the dead, who go the Realm of Flames after their lives, are the medium for storing and accessing information in Flamespace. This is the collected stored data, which is to say, the Obsidian.

Flamespace is also useful for controlling elementals remotely and spying anywhere where there is a flame to use as a viewpoint. The smaller the flame, the more difficult running it is, and expert runners boast of using candleflames, while others still wonder if it would even be possible to run a lit match.

One doesn't physically enter Flamespace (it would kill a living person, though perhaps with the appropriate fire-protections...but no, pyronautic exploration has not been achieved yet), instead one projects their soul through the Obsidian, using the web/network of dead spirits as their pathway for projecting their consciousness through the Realm of Flame.
