Amber Emissary is the newest ARG in the "Twelve Monoliths" series of
unfiction works. Several short stories that play out in an expanded
universe.

The eponymous Amber Emissary hints toward the connection of a string
of grisly murders that push its victims to an underworld powered by
their flesh. Upon the final victim, the gates open and some of the
reformed bodies return to the world above, and suddenly, somewhere, a
strange computer boots on with a strange, repeating message.

"I contain multitudes."
