Guild Wars 2

I done Underground Facility Fractal.
Received: Ancient Dwarven Texts.

Went to the Durmand Priory and I talk to Ogden in the office,

I only get the option:
I need to do some research in the Special Collections.
Never mind

Do I need to do some research in the Special Collections.?

I have managed to solve the problem.

I have all the other legendary Weapon collections part 1 unlocked.

The Dreamer 1: The experimental Short Bow.
One of these collections requires you to talk to Ogden and do some research in the Special Collections.

Love among the Weeds
Hint: Read about the quaggan love potion in the Durmand Priory.

The Dreamer collection was preventing the Nevermore Collection from activating, I guess it only allows one collection event at a time.

Once I had completed the Dreamer Collection piece, the Nevermore collection activated and I was able to do the Nevermore collection Piece.

I had all Vol.1 Legendary Unlocked, and one thing is blocking my way of completing the quests is what the OP said,

Dreamer is the cause,
Now I’ve got my nevermore.
