Once you successfully complete these patrols you will get Skyburners Security Pass from the last mob you kill for the tasks. These tasks have a timer on them so do not waste time. Usually killing cabal in the area and scouting places.

Inside the opening is a console you can interact with. There is an opening in the side of the ship you can reach by jumping over nearby metal beams. With deployment codes go to the Mausoleum towards the entrance into the cabal ship (and where they are usually fighting the Hive). This will summon a Cabal Champion (via dropship) and once you kill him he will drop Skyburners Deployment Codes. There is a console there you will be able to interact with. Once you get the Command Beacon go inside the Cabal ship at Hull Breach and turn left as you enter. First, you will need to kill Cabal Centurion, Colossus and Phalanx on The Dreadnaught (plenty of them at Hull Breach and Mausoleum) until they drop an item called Skyburners Command Beacon. You will have to do several steps in order to acquire this rune. We included the Grimoire card numbering in the information bellow, so you can hunt for those that you are missing. You can see the Calcified Fragments’ numbers in the Grimoire cards section of the game (on the Bungie website). Fragment location guides bellow are ordered in the way we found them and grouped by the area and mission they were found in. You should also turn those in as soon as you collect them (to avoid the bug) and you will be rewarded with the Reciprocal Rune. Eris will give you a follow-up quest called Shattered Past that asks you to collect 5 additional fragments.

Make sure you abort your mission and go back to the tower to turn it in, because it might get bugged. There is also a quest you will get from Eris Morn when you collect your first fragment. After collecting all fragments, players will be rewarded with a special reward, but we still don’t know what it is since no one managed to find them all. There are 50 well hidden Calcified Fragments scattered through the new missions. Calcified Fragments are new items in Destiny, which became available with The Taken King expansion.
