Abronath

The Abronath was an ancient weapon of mass destruction created by the now extinct "Ancient Ones" of Altamid.

History
Sometime prior to the 2160s, the indigenous inhabitants of Altamid departed the planet, leaving behind sophisticated mining equipment, a drone workforce and advanced energy transference technology capable of extending humanoid lifespans. Having engineered the Abronath, the Ancient Ones split the weapon in two and set the pieces adrift in space in the hopes that the weapon would never be found.

Following the crash of the USS Franklin on Altamid in the 22nd century, Krall began a search for the Abronath, capturing vessels from orbit and marooning their crews on the surface in his quest.

While Krall was successful in retrieving one section of the Abronath, the second lie in the hands of the Fabona, who passed the artifact to the United Federation of Planets to be presented as an offering of peace to the Teenaxi in 2161. Mistrustful of the Fabona and suspicious of the inactive weapon, the Teenaxi refused to accept the Abronath and Captain ordered the artifact stored in the archive aboard the USS Enterprise (alternate reality).

Using a captured Federation probe, Krall was able to locate the Abronath aboard the Enterprise and lure the ship into the Necro Cloud where his forces destroyed the Enterprise, scattering its crew on the surface of Altamid. Discovering the Abronath had been placed in the safe keeping of Ensign Syl, Krall activated and used the device on the Starfleet officer to demonstrate its power. Krall then departed Altamid for the Starbase Yorktown where he hoped to release the weapon and wipe out its millions of inhabitants – a first strike against the Federation.

Captain James T. Kirk and the former crew of the Enterprise – now aboard the repaired Franklin – were able to intercept Krall at Yorktown. Kirk engaging in hand-to-hand combat with Krall and causing the Abronath to consume and kill Krall, before both were ejected into space.

Specifications
The Abronath consisted of two parts: a metallic ring and a hexagonal center piece. Once the pieces were joined and submerged in a black fluid, the weapon was armed and could be placed in an aperture or ventilation system where the fluid was then be released in a cloud-like state. Upon contact with humanoid life forms, the Abronath's emission would instantaneously break down its target leaving little-to-no remains behind.
