Pelos

Pelos was the homeworld of the Pelosians. Some time before 2270, a dense interstellar dust cloud settled around Pelos' star system, causing agriculture failure and widespread famine. The cloud also triggered increased solar flares and suppressed the stellar magnetosphere which protected Pelos from cosmic rays. The famine and the radiation ravaged the Pelosians' immune systems and plagues ran rampant. That year, the USS Enterprise (NCC-1701) discovered Pelos and covertly gave aid to its population to prevent their extinction.
