It seems much of Devra's early work is being filled in the last week. I have collected many of the pieces at the Niantic Wiki page for 13 Magnus - http://niantic.schlarp.com/investigation:characters:thirteen_magnus
It seems Hank and Devra met 20 years ago at Areicbo - leaving some of the items in the original Tycho posters for reinterpretation. We also begin to see the connections between Hank, Dr. School, Dr. Wright and Devra.
We also see that Calvin Ezekiel has been chasing something for a very long time and using many of the same chess pieces.
Lastly, Devra may have been exposed to glyphs some 20 years ago (as well as Hank and any who saw those photos). What does this mean? Is this why in the Roland audio tapes he mentions it is like Devra knew what he was thinking????
Much more needs to be teased out.
