The Destiny 2: Edge of Fate expansion presented a pretty lore-heavy campaign for the players, and one of the quests you’ll come across is the Dark Academia. This is a fairly simple side quest, but the problem that you’ll face is getting access to it.
As it happens, you’ll need to open a door to pick up the quest, but the game doesn’t exactly tell you how to go about doing that. Here’s a detailed guide on how to unlock the door to the Dark Academia in the game.
Unlock the Door to the Dark Academia in Destiny 2

You have to destroy three Fuses and then charge up a terminal using Matterspark to open the door to the Dark Academia. The problem is that the Fuses are a bit hidden, and you’ll need an ability called Mattermorph to access them.
You get this ability while playing the main story of the Edge of Fate. Once you have the ability and when the Dark Academia quest becomes available, follow the steps mentioned to unlock the door.
Step 1: Destroy the first Fuse

Mark the quest on your map, and reach the location. Walk up front and you will notice a locked door and a terminal surrounded by a barrier.
From this door, move back, take a left, and look down. You will notice the first Fuse placed inside a vent. Simply shooting it will destroy it.
Step 2: Access the Mattermorph

Once you have destroyed the first Fuse, you’ll notice a red light over the door, that means the first step was successful. Now, keep moving left, and you will eventually come across a ramp.
Walk up, look right, and jump over a pipe moving surrounding a wall. Keep moving straight while walking over the pipe and you’ll notice the Mattermorph.
Interact with it, and now you can use it. If you have forgotten, your melee button will trigger the Mattermorph ability.

Step 3: Destroy the second Fuse

Once you have the ability, look back and walk the same path as you came. Jump over the ramp from the pipes and you’ll notice a Darkness door right below where you jumped.
Use your Mattermorph ability to break the door, and now you’ll come across the second Fuse inside a vent. Break it and now you only have one left to go.
Step 4: Destroy the final Fuse and pick up Matterspark

After destroying the second Fuse, keep moving up the ramp, and you will notice a Darkness-covered Pipe. Throw the Mattermorph melee and you will find the Third and final Fuse. Destroy it, and now the barrier that covered the terminal near the door should be available.
From where you destroyed the Fuse, look around a bit, and you’ll notice the Matterspark right near you. Activate it, visit the initial location, and charge up the terminal that got unlocked after destroying the third Fuse.
Interact with the Terminal in your Matterspark form, and the door to the Dark Academia is now unlocked. You can go through and continue your adventure from there.
