Symbol of the Sediao

Headquarters Guāng dǎo (Luminous Island)
Affiliation Mòrì Shāshǒu
Purpose Various

An ancient organization of prominent assassins that's former purpose was to eliminate any threat to any of the four nations' royalty, a new leader has taken the highest ranking possible in the group and has shifted it into a new direction; unleashing a dark and powerful beast intent on destroying all life.


Most of the history is known to the Sediao alone but what is known is that they have always been around hidden in the shadows waiting to strike those that get in their way fast and deadly but the threat they present is now more dangerous then ever as they threaten to assassinate or capture people of royalty and possibly going after the Avatar himself


Any rank under third has to help the Sediao in a certain way (fulfilling contracts, organizing hits, and paying a monthly membership fee) but the positions aren't fixed. The rules of the Sediao are not clearly defined or demonstrated, and the nature of the organization is somewhat questionable. It is known that killing higher-ranked members allows one to climb higher in the association, though the exact benefits of doing so, aside from challenge and prestige, are not made clear. Presumably, higher ranked assassins receive better assassination contracts and pay (either through the Association itself or outside parties). A ranking fight is organized at the request of the challenger, The location is picked by the challenged assassin.
