(ENT novel: Kobayashi Maru; TOS movie: Star Trek II: The Wrath of Khan)
The year 2244 saw the "intermittent" war between Altair VI and Altair III heat up, leading to the most devastation in Altairian history. (ST roleplay module: All Our Yesterdays: The Time Travel Sourcebook)
By the 23rd century, Altair VI was regarded as an excellent shore leave location and was an important planet within the Federation.
Altair VI's colony world of Altair IV declared independence in 2267, which sparked a brief conflict ended by Federation peacekeeping forces. When a new president was inaugrated, Starfleet placed the greatest emphasis on showing support by assigning three Constitution-class starships to observe the proceedings. In 2285, the government on Altair VI continued to govern both worlds pending a resolution from the Federation Diplomatic Corps.
The waters of Altair VI are rich in natural minerals that are renowned for their medicinal properties.
