Kharzh'ulla

Kharzh'ulla is a Tellarite colony world that possesses one of the many wonders of the galaxy, which is The Ring. The Ring was a massive orbital structure that was serviced by a series of 'space elevators'. Unfortunately, during the time of the Dominion War, the Ring was heavily damanaged by a Jem'Hadar attack which weakened its structure and nearly resulted in its collapse which would have potentially killed millions on the planet's surface.
