The Kalandra Sector is one of the most densely populated
regions in the Alpha Quadrant, with the native worlds of
the Farians, the Galdorans, the Klaestron, the Kressari,
the Trill, and a Federation colony on Caldik Prime.
United for three centuries by a loose trading alliance,
the sector had known peace for as long as the worlds in
that sector had the capability to travel in space.

This all began to change in the early 2300s.  A
neighboring race known as the Tzenkethi started raiding
the Trill System.  This continued for several months
until the Trill were admitted into the United Federation
of Planets.  In late 2310, the Tzenkethi started with
even more raids.  With that, the Kalandra Interplanetary
Coalition (referred to commonly as "The Coalition") was
formed in March of 2316.

By November 2325, the Coalition feared an invasion was
imminent, and they sent out a call to the United
Federation of Planets to provide assistance.  The fact
that the Federation colony on Caldik Prime and the
Federation member world of Trill were in the direct
line of fire from Tzenkethi assaults forced their
involvement.

Along with the Coalition, it was determined that a
central base of operations for starships would be
required as the facilities at the Caldik Prime
installation were not able to support increased
starship traffic.  In May of 2327, construction was
completed and the station was christened
"Delos Station."
