Euphrati Seal

The Euphrati Seal is a small device designed to permanently imprison immortal beings. Powered by an Old Brethren derived orb, these are designed to completely suppress their target's powers and seal them in a pocket universe.

History
The predecessors to the Seals existed well before the First End, when Transcends had begun to appear in significant numbers. The first designs of these weapons were large and bulky, and instead drew their power from a wormhole link to a large reality anchor to suppress the abilities of their target. These proto-Seals became obsolete with the introduction of the Opal Light, as maintenance heavy imprisonment became less desirable than simply mind wiping the targeted Transcend and rendering them incapacitated.

The first true seals were developed shortly after the Ascension Wars, some time after first contact with the Old Brethren. Study of various Brethren specimens and how their terraforming fields worked lead to the development of more efficient devices that could precisely target a Transcend without causing nearby reality warping technology to cease function. After being paired with another device that partitioned off the space the target existed in, the first Seals were then manufactured.

Mechanism
Usually taking the form of some kind of weapon, the Seal is designed to project an Old Brethren derived terraforming field onto the target, causing an effect similar to the strongest reality anchors and suppressing the target's reality warping abilities. Once the target's abilities have been suppressed the space that the target exists in is cut off from the rest of the universe. Due to the nature of Old Brethren terraforming fields, the target's abilities are at least partially suppressed, if not fully so, and paired with the spatial partitioning, makes for ideal long term imprisonment of reality warpers.
