Exalted Concept: Abyssal Stealth charm that remarks the target as unaware because the big tense dramatic reveal comes and it was a cat or a coworker or the neighbor or something that gets the blame instead.

...please

Caveat that it's usable only once per scene.

oh my god

Also, Abyssal Linguistics:

"Elephantine Misdirection"

Or to make that second part less shitposty; we were joking about the Exalted Modern Shard and the fact that it gave Abyssals a supernatural screamer as a Computer charm.

that was the fucking best charm

I had my Abyssal in Caitlin's game a while back blow up his ex's smartphone with it

But given that Solar Linguistics is all about what kind of message can I subtly sneak into the real text of this book, I could see the Abyssal version being something overt and either single target, or, like how a lot of the horror ARGs did it, hitting everyone but a single target.

Poor feckless local lord who's actually doomed can't see that the random missive pinned to the door begins detailing horrifying shit halfway through.

...the idea has been refined down to it is a targeted social attack that hides the true nature of the message sent from the target, instead instilling an intimacy of incredulity that gets reinforced when people try to persuade you otherwise.
