Weytahn

Weytahn was a Andorian colony on the a formerly uninhabitable class-D planetoid, approximately as large as Earth's moon, Luna. It was the home to a rather pernicious mutagenic pathogen that was capable of harming Humans, but did not affect Vulcans. Weytahn was located on the frontier between Confederacy of Vulcan and the Andorian Empire. Both sides claimed it belonged to them, having nearly gone to war over the planetoid twice.

Weytahn was terraformed by the Andorians in the 2050s for the purpose of establishing a colony there. Once an atmosphere was developed, they established a settlement. Due in part to its relatively close proximity to Vulcan territory, Weytahn was believed by the Vulcan High Command to be a covert military installation.

Vulcans and Andorians eventualy reached a Territorial Compromise, which took eight years to draw up and was later viewed by Andorians as the source of a century of aggression.

In 2097 the Weytahn Crisis erupted with the refusal of the Andorian settlers to let the Vulcans inspect their colony provoked the Vulcans into annexing the planet, and it was renamed Paan Mokar. Weytahn's settlers were forcibly removed and placed in refugee camps. The new situation was codified in the Treaty of 2097. A surveillance satellite was put into orbit to monitor the agreement.

As part of the 2097 Weytahn Accords, the Vulcan-controlled 47 Ursae Majoris-system was ceded to the Andorians, and settlers arrived the following year. Eleven-months after the colony was abandoned when most of the local plant life proved toxic to species to cobalt-based blood, namely Andorians. The result was the Andorians believed the Vulcans had intentionally ceded the planet knowing it was dangerous for Andorians.

Weytahn remained deserted until 2152, when Shran, an Andorian regimental commander, landed a force on the planetoid and occupied the settlement in an attempt to forcibly rescind the Weytahn Accords. The Vulcans attempted to enforce the Treaty of 2097 and managed to regain control of half of the colony. They, however, suffered several casualties, including two dozen wounded and three taken hostage. Shran agreed to discuss terms for their safe return, but only if Jonathan Archer would act as mediator. Archer was able to get the two sides together and establish a common goal for them.

The Vulcans eventually agreed to cede ownership of the world to the Andorians.
