Finding the Destiny 2 Perdition Lost Sector can be a little tricky as it's in an easy-to-miss cave in Cadmus Ridge on Europa and isn't marked on your map. This is a particularly important Destiny 2 Lost Sector too, as you'll need to venture inside if you want to get the Crystocrene armor Class Item - if you don't already have this armor quest, make sure you've progressed through the Destiny 2 Beyond Light campaign enough and then collect it from Variks. Here's where you can find the Perdition Lost Sector in Destiny 2.
How to get to the Perdition Lost Sector in Destiny 2
To reach the Destiny 2 Perdition Lost Sector, head to the northeast side of Cadmus Ridge and look for the ice tunnel. To the right of this tunnel is a narrow cave entrance, and you'll eventually reach Perdition if you follow this linear cave.
As you run through the ice cave, you'll eventually reach the remnants of part of the Exoscience facility. Press on through a few corridors and you'll reach the Perdition Lost Sector proper, with lots of Vex enemies ready to greet (fight) you. battle through three main areas and defeat the large Minotaur boss at the end to unlock the Lost Sector chest and loop back to Perdition's entrance, so you can leave back through the ice cave. With the Lost Sector cleared, it'll now appear on your map too.
If you're specifically looking for Aged Armor parts to complete the Europa armor set quests, you'll need to find a sealed Stasis chest inside Perdition - getting this chest will bag you the Crystocrene Class Item for your current Class. Luckily the required chest is easily found under a catwalk right as you enter the first room of the Lost Sector. To find the other four Destiny 2 Europa armor pieces, you'll need to explore the icy moon to find nine other Stasis chests, although this is the only one found inside a Lost Sector.
