A little while ago I finished my Ultramarines Librarian, but wasn't able to get good pics until last night. So, here he is, along with his fluff:
Epistolary Librarian Laetus Falco
From his induction into the Librarius of the Ultramarines, Laetus Falco displayed a penchant for using his powers to unlock the physical and psychic potential of his battle brothers. Those Marines who go to battle beside the Epistolary find themselves possessed of great strength, unassailable mental fortitude, or able to endure or recover from the most dire of wounds.
As a Codicier, Falco was able to use his powers to keep his mentor alive long enough to banish Nodosus, a greater daemon of Nurgle, back to the warp. Falco's mentor died shortly after, but lived long enough to pass his force staff, Reach of Empedocles, to Falco. He has carried it ever since.
I used a darker blue for his armor, since the Codex Astartes indicates that Librarians are marked out by a deep blue. I use a lighter ultramarine shade for my army, so I just stopped one shade darker. You can see the difference in the second picture that shows the shoulder pad with the Chapter icon on it.
His backpack is magnetized so I can swap in a jump pack if I want.
This was a fun model to paint, and I'm really enjoying all of the new clam pack characters GW releases. I'm thinking about painting the Reclusiam Command Squad Chaplain next, after I've finished all the other Ultramarine models in my queue.
