Mara

About
A shape-shifting entity that feeds off the misery of others for the fun of it. How "Mara" got here on this Earthly plane is unknown at the moment. What we do know:
 * She got bored and preyed on Winnifred
 * Set up participant Risa with a staged kiss
 * Photographed (possibly by the Stranger) without Risa's consent
 * Photographs shown at the very end of Stratagem to Winnifred just to break her heart.

Associations
Appears to have some association with The Stranger. 4/5/18: Stranger and Mara are one
 * Read her journal (which was in The Stranger's possession during Stratagem) for more insight.

Important Notes
-Has been giving chess pieces to several Professors. Claims that the chess pieces "...it'll become clear why it matters".

- Claims that she is not The Veiled Woman.

Update: During Stratagem (3/10/18) Mara revealed herself to be, in fact, the Veiled Woman.

-Claims she has been lurking in Slack since January--became known and active Feb 21st when she turned Theseus off with a command . Notably, Jonathan Everett used that same command a few days earlier and it didn't work....

-Privately expresses frustration that Winnifred publicly accused Mara for being The Veiled Woman. -Mara is not only The Veiled Woman but she's actually a shape-shifter. Her primary form is a female humanoid.
 * This was done to just manipulate our feelings.

-She is Stranger's other half (think left brain, right brain)

-After several professors performed a ritual with The Stranger, Mara went on to Slack and command Theseus to archive most of the channels and became the owner of Slack. She claims this is what we want.

-She seemed to have facilitated Athena's meet with The Stranger, as revealed here.

Theories/Archived Theories
While Mara has been confirmed to be a shape-shifter this doesn't exclude her from being something else. Below are a few theories that Professors floated around on Slack shortly after her arrival.

The profile picture of a black queen chess piece has been causing wide speculation and theories that Mara is The Queen. Other theories:
 * Mara is death
 * Mara is The Veiled Woman


 * Mara is actually this unnamed woman
 * All or some of the above.
