++++++ Report to Inquisitor Marleck on the Shadow Sentinel Librarius ++++++
For hundreds of years it has been assumed that the Chapter lacked the gene required to manifest psychic powers (this time fueling rumours that they were an offshoot of the Black Templars). This opinion was furthered by the number of Culexus assassins that had been seen operating in tandem with the Sentinels in an apparent effort to neutralise enemy psykers.
It is this agents opinion, that this is another example of the misdirection constantly employed by the Chapter. Although he cannot offer hololith evidence, this agent has personally observed at least one Sentinel manifesting powers from the Librarius Discipline. Whether this Marine is an aberration in the Chapter or one of many Librarians rarely seen, he cannot confirm.
Of probably greater importance is the question of why have they gone to such lengths to conceal their presence.

The latest edition to the Shadow Sentinels is one of the very rare Chapter Librarians.
I kept the paint scheme in the same simple green and silver but added a bit more detail, a completely unblended variation of colours on his hand because, you know, that’s what psychic powers being cast look like… I also experimented on the sword (unsuccessfully) using the Nihilakh Oxide after I had edged it etc. with the various blues. At present I’ve not gone back to clean that up but will do so.
