Sherman's Planet

Sherman's Planet was an M-class world near the Federation-Klingon border.

In 2267, both powers attempted to demonstrate, per the requirement of the Organian Peace Treaty, that they were best able to develop the planet. The introduction of quadrotriticale to the planet helped to tip the balance in the Federation's favor (as the Klingon's covert attempt to poison the grain helped tip the decision against them).

By 2376, Sherman's Planet was a relatively prosperous Federation colony with a population of approximately three million, noted for its unique varieties of grapes and wines. That year, a mysterious epidemic was unleashed across the planet, causing Administrator Orosz to declare marital law and impose a planetary quarantine. The disease, dubbed "Sherman's Plague," was cured by a radical, gene-altering treatment devised by Doctor Elizabeth Lense. (SCE eBook: Oaths)
