Divinipedia is a universal encyclopedia in Kid Icarus: Uprising. It is similar to an online database, such as a wiki.
Divinipedia contains many things, such as facts about the gods and goddesses and information about the various races and armies around the world. Its existence has not been completely confirmed, as Pit is extremely skeptical of it when Pyrrhon mentions that he used the encyclopedia to gather some knowledge of the Aurum.
Pyrrhon is the main user known in-game, but it is possible that Pit got the link he asked for from Pyrrhon. However, it is almost completely confirmed that only the divine pantheon knows about it, if it does exist, as there is never any human mention of it or anything about the humans inside the content that we know of.
