Hm, so Arkaim points out that this effect had the wrong image uploaded on the wiki… so I updated to the picture with the eyes on it. But in the process I noticed that this is effect 399, not effect 398 as previously listed on the wiki.
So there's either a bunch of sloppy wiki editing going on here or there's two Hide Your Emotions effects, 398 and 399, with different pictures but otherwise same effect. (See Fighting the Sun as precedent).
Either way, keep an eye (or two) out.
For the record, 399 is:

Some might call it cowardice, but they are only betraying their own fear. Everyone recognizes how well a stony mask might help you in gambling, but the real cowards are those who refuse to admit how much of life is gambling.And those are the cowards who will look on you in fear. Those are the cowards who will break themselves upon you like waves on rocks.
Effects
+2 Etheric Power
+4 Will
EDIT: Nevermind, ignore all this. 398 was on the id list twice so it screwed everything up and I assume the picture was just mistakenly copied from another mask effect.
