Theta 4 - Haigon

Theta-4 is a Haigon fleet created with the premise of guarding the borders of the Chartihli system from any possible threat. Theta-4 at its peak was made up of 207 ships, most of which would not survive the Mystic invasion.

MYS Invasion of Haigon
The Chartihli system contains multiple vital Industrial worlds that produce components for the manufacture of more complex items. Due to the indispensability of these worlds during the Mystic Invasion of Haigon the High strategic command of Haigon mobilised 163 ships to defend the system.

Theta-4 during the latter phase of the Mystic Invasion expanded to 207 ships, although many of these ships would be diverted to defend other key systems. MYS forces were easily able to overrun the diminished Theta-4 and subsequently seized control of the Chartihli system. Following the loss of Chartihli the remaining ships and newly assigned DPC Expeditionary Forces would be assigned with the eventual recapture of Chartihli but were first assigned to the desperate defence of the greatly diminished Haigon.

As the Mystic Invasion of Haigon came to a close with an overall military failure for Haigon and the DPC Expeditionary Forces, the remaining vessels for Theta-4 along with the remaining DPCEF ships were granted safe passage across the DPC border and were granted safe-haven and opportunity for resupply at any DPC Military port.

DPC-MYS War
Theta-4 was put under command of the Haigon Exiled Forces which were operating inside of the DPC to aid in the defence of DPC assets under promises of the liberation of Haigon in its entirety with promised expansion.
