The city of Neomuna is a Vaporwave aesthetic dream. Bright lights, retro look, palm trees, and lots and lots of purple. It would be a treat to actually visit this place and see the sights. However, that will have to wait because the city is under siege from pretty much every enemy that the Guardians and The Traveler have.
Everything that could go wrong with Neomuna, went wrong the moment The Witness came forth. However, you can still look around while shooting down bad guys, like going through the Ahimsa Park Lost Sector.
Ahimsa Park Lost Sector Guide – Destiny 2
Open your map and head to Ahimsa Park. You should be able to see the small little icon that contains the Lost Sector in Ahimsa Park.
Now that you know where it is, the next step is to actually find the entrance.
The entrance can be found here on the side of the ship. You will have to drop down to the ground below and hug the wall to avoid falling as you make your way to the entrance.
When you enter the area, you will find Cabal enemies patrolling around, fully unaware that you are there. Take advantage of the situation and ambush them.
Fight through until you reach this area. You will need to reach the other side to continue the Lost Sector.
To the right, there is a pathway you can take that will serve as a safe jump toward the other side.
Continuing onwards, you will soon enter this hall that is full of Cabal. Use the structures around you to take cover, as they will bombard you as soon as the fight starts.
Enemies will keep spawning until you exit the room.
To get out, you will need to defeat the enemies until they drop a Bloom. You need two of these in order to open the door on the other side. Once the door is open, keep pressing forward.
Eventually, you will reach the room where the main boss is.
Valus Tharum, Gladiatorial Overseer will be your enemy. He acts like any other Cabal Colossus, except he deals more damage.
Simply defeat Valus Tharum and you will be able to open the chest and complete the Lost Sector.
