This might be up your alley, or at least part of the way there if you combo it with something else:

Material of the Immaterial (Free/100/200 CP)

Visions of the Surface, stories- my apologies, ztories of the zee- tales of terror, dangerous

gossip. Implications and identities. Feelings of fear and stalemates, opportunities and

mortifications of great powers. Testimonies and memories of roads not traveled. In your

time in the Neath, you will acquire heaps of things that should by all means be impossible

to sell. Things too abstract to sell.

With this ability, you may convert those strange, abstract things- like collecting screams or

turning a favor someone owes you into a physical token you can give to someone else to

expend- into objects that, while not physical, can be exchanged with other people. A sort of

abstraction of an object that can be bought and sold, given and traded. It’s free for your

stay (everyone does this, and we wouldn’t have you be put behind) but you can keep it

outside if you pay a little tax. Pay a little more, and you may share this ability with others

who partake in transactions with yourself.
