This papercraft is Rune, based on the stealth action-adventure video game Dishonored, the paper model is created by Sinner. Runes are decorated pieces of whale bone that are used to acquire and improve supernatural abilities; the more powerful the ability, the more runes it requires.
In Dishonored, a maximum of 39 runes are obtainable in a single playthrough, but 58 would be needed to fully upgrade every ability to Tier II. Therefore, Corvo Attano must assign them according to the approach he favors the most.
The Outsider claims that the first Runes were created centuries ago by an ancient and long gone civilization, saying that many of the runes in Gristol were found washed up from the water. Granny Rags is able to create Runes with an ability given to her by the Outsider. [Source: wikia]
