Clipse

The Clipse are an alien species and members of the Cabal Loyalist Faction under Emperor Calus in Destiny 2.

History
Originally a technologically advanced yet peaceful society, the Clipse were invaded by the Hive who used a gamma wave to destroy their technology. The Hive proceeded to poison the atmosphere of the Clipse homeworld and rain celestial objects unto the surface destroying the Clipse civilization.

The Clipse managed to recover and rediscover subsistence farming, but were constantly under attack by aliens that came from the asteroids sent by the Hive. To survive the Clipse became more militaristic

Emperor Calus, in his exile, discovered the Clipse and offered them a place at his side. When they refused he resorted to force to conquer them. After the war he provided aid to the Clipse, but was unable to restore their planet's atmosphere.

Culture
The Clipse were a peaceful society but due to circumstances and the need to survive, evolved into a martial culture with an obession with guns and war.
