Pre Federation Era (2153-2161)

On April 2153 the Earth exploration vessel enterprise departed to a region of space 50 light years away from the solar system called the Delphic expanse, their mission to prevent an enigmatic race known as the Xindi from developing a super weapon being built to destroy earth and humanity. Already a month earlier on March 2153 the Xindi had attacked with a prototype probe that cut a huge swathe all the way from Venezuela to Florida. 7 million people lost their lives.

During their quest the crew of Enterprise discovered that a mysterious race known as the Sphere Builders referred to as "the Guardians" by the Xindi and "the Makers" by the Triannons had in fact been manipulating the Xindi into destroying humanity. This is because in the 29th century humanity and Xindi would combine forces and thwart an invasion of our galaxy which they had planned. By February 14 2154 the mission was a success the super weapon was destroyed in orbit of Earth having been hijacked by the Xindi-Reptilian faction.

Unfortunately contact between Enterprise and the Xindi reignited a long dormant Xindi Civil War for two days. Afterwards it was thought that all Xindi factions would rejoin the council and continue their efforts to maintain unity, with the crisis over both sides returned to the own affairs.
