The description isn't absolutely clear so:
You need to get 4 "Attunement Codex" to drop from nearby Mawsworn. Take the 4 "Attunement Codex" (plural of codex is codices) to the 4 terminals in the area and click on the terminals.
There are elites that drop the 4 "Attunement Codex" but there are also non-elite Plunderers all over the area that have a higher drop rate and are easy to solo if you can pull them without also pulling nearby elites.
I have an add-on that points out which mobs drop quest items but it didn't work for this quest.

Dropped by the Mawsworn nearby. Pro tip: join an [npc=179006] killing group and drag all the mobs around to it.
Seems odd that with all the solo stuff and everything we have done so far to tag this questline on at the end that is pretty tricky (or damned slow) depending on if you're squishy or not. Think I missed the bus when people were grouping up for this.. oh well :p

What to do
Description
The architect set forth these tasks: Stay safe. Restore the Protoform Repository when danger passes. The mortal knows the cyphers. The mortal will help with the tasks. Attuning of the energy terminals is required. Each terminal requires a codex. Invaders pilfered the necessary codices. Go.
Where to go
Pins are the quest’s own POI points from the current retail client, projected onto the in-game zone map. The game marks one blob as the quest’s turn-in; the rest are objective areas. Points that fall outside a map’s window are dropped rather than guessed at.
