Well, mostly the idea of the shadow coating was just a concept, i was totally ready to scrap it.
I want the entity to be unidentifiable. A lot of this is inspired by a Black Market info dealer in concept.
Some off the issues I'm having is coming up with a unique idea beyond one idea about how as the SCP is near someone, it begins to psychically extract information, using it to control a situation, but it can be over come by the emotion of some memories, due to its own inabilty to naturally produce emotion. So feeling such raw emotion in it's self can overwhelm the entity.
Like, for example, if the entity gathers a rather happy memory, it will be overcome with joy and become giggly, laughing constantly.
Though if it takes a rather sad memory on accident, it will be overcome with a depression like state.
A kind of bipolar personality that is directly affect by the person the entity is currently trading information to.
Also, along with this, I rather am of the notion to make the entity trade information for antique items or family heirlooms. Though I don't know…
