There are several new activities and events in Destiny 2's latest Season of Dawn update. They all revolve around Osiris and the sundial, which are on Mercury. You start working with Osiris shortly after talking to Ikora at the tower and starting the A Matter of Time quest. Eventually, you'll have the chance to grab An Impossible Osiris Task, and there's a quest step called Corridors of Time.
You can do this quest alone. However, it does help bring in a fire crew to get it moving faster.
part 1
Corridors of Time occur after you return to Osiris and return the Vex components you acquired in the Big Vex Hunting section of the quest. You will not have a Corridors of Time quest in your quest menu. However, to the right of Osiris, you will notice that you can now interact with the sundial to begin this quest. Approach and start it.
The Sundial interacts with the shotgun you crafted in the first quest you did before an impossible task called Recovering the Past. Proceed into the clean room and go through the doors. During the first part, there is a room full of Vex that you have to kill. Every now and then a little robot will trap you for a shield. You can shoot yourself, but if you shoot the drone before it gets to you, you won't have to deal with the shield. Kill all Vex.
You'll walk through several of these oddly lit rooms and through the unblocked doors with a glowing white light coming out of them.
Eventually, you'll reach a point where you'll be given a new quest objective: Search for Saint-14.
Now you take on older Vex and Fallen as they attempt to get to Saint-14 and take him out. Continue the mission destroying them all and everything in your path. When you find Saint-14, he's surrounded by Fallen who uses a shield to protect himself. Take out the Fallen and help him and any Fallen who land there.
After the first wave, House of Rain Servitor and House of Rain Walker appear in the fight. Take out the Servant before you find the Walker because the Servant is protecting him. After killing these two, all the minions disappear. Go up to Saint-14 and talk to him by arming the Perfect Paragon. Then you will come back. This concludes the first part of the Corridors of Time quest.
The next quest step will be posted at a later date.
