First, head to the Hull Breach where the Cabal ship is and keep killing Cabal enemies out the front until you see the message that they are sending reinforcements. When they send reinforcements there will be a special yellow Cabal and it will drop the "Skyburners Command Beacon". Go inside the Cabal ship and immediately to your left there will be a computer/screen that you can use the beacon on. Use the beacon and it will summon their champion outside after a little bit. Kill the "champion" of the Cabal and then pick up the Skyburners Deployment Codes he drops.
Once you have the Skyburners Deployment Codes, head to the Mausoleum from the Hull Breach and head to the left where the Cabal are. Just before them there is a ship with a window up to your top left that has sceens/computer/tech in there. You can then use the Skyburners Deployment Codes in here, and it will begin the quest chain (it can vary, this is just what mine was). First it is clear enemies.
