[Name: Immortal Binding Keystone
Grade: Tier-5 Origin Rank
Details: The Immortal Binding Keystone is an Origin-ranked treasure created to suppress chaos and bind everything. It is not a weapon, nor is it a tool meant for direct combat. Its true purpose is to stabilize space, seal violent energy, and prevent the world from collapsing under overwhelming power. Wherever the Keystone exists, the surrounding space is forced into order almost in an instant, no matter how terrifying the battle becomes within it.
The Immortal Binding Keystone was created to imprison Immortals, restrain divine disasters, and seal unstable domains that threatened entire worlds.
Although it is only a Tier-5 Origin-ranked treasure, Immortal Binding Keystone is extremely rare even among Origin treasures. Its presence represents absolute authority over spatial stability, boundary laws, and suppression order.]
