Something really weird is going on with the Corridors of Time in Destiny 2, and it looks like the Sundial Obelisks hold the answers.
It's Tuesday, and you know what that means: it's reset day in Destiny 2! And as with every reset, things are different now. Eva is gone for another year, the NPCs aren't handing out gifts if you give them fresh baked goods, and Osiris has a brand new quest to send you into the Corridors of Time once again.
Only he doesn't make it obvious. As usual, Osiris isn't a blinking beacon on your destinations to indicate that he's got a new quest for you. You actually have to go to the Sundial and talk to him in order for the quest to become available.
That quest is called "Explore the Corridors of Time." The description makes it sound like you're just taking a jolly-old romp through the timestreams to see whatever you can find, which doesn't seem like a terrifically safe way to time travel, but whatever.
Those heading into the Corridors of Time blind will be shocked to find that every corridor is now open and there’s no indicator on where to go, which makes the whole place a bit of a maze. You can easily get lost in time, but we’ve got some inside info to help direct you.
The key is in the Sundial Obelisks that are on Mars, Earth, The Tangled Shore, and Nessus. Each displays a pattern of symbols that corresponds with the symbols above each door in the Corridors of Time. Follow the symbols from the upper-right corner in a clockwise spiral ending with the center symbol and you’ll know which corridors to traverse.
According to Forbes' Paul Tassi, there are 19 different paths that lead to 19 different pieces of lore at the end of them. The symbols on each obelisk change every hour to reveal a new path, meaning we’ll have to wait 19 hours before we know each one--unless some folks blindly stumble into paths first.
The r/raidsecrets subreddit is busy documenting each path as they’re discovered, so check there for an updated list. So far it doesn’t look like you get anything other than lore, but that’s more than enough for some Destiny 2 players.
