Story related, can't be missed.

To earn this trophy, you will need to encounter the Warden in Duskprism and speak to it. This is a story related event and needs to happen to progress through the game. To get to Duskprism, you need to complete the events in Mornsea and Eventide and collect the wind from The Gossamer Flock and Levaithan Demigods. The wind will then be transferred to the glowing orb in the middle of the Sunchamber which will then power up the Green Transverse Gate within the mountain that is below the glowing orb. This Green Transverse Gate will take you to Duskprism. Activate the switches and fly into the blue orb and activate it by smashing buttons. You will then be launched towards the door leading to a large purple area. Here the Warden will talk to you and once the conversation is over, the trophy will unlock.
