"I like being here, in this umbra."
Alex has never known anything outside of The Books. All of Alex's life, they've been alone. The only thing Alex knows is the dank pages of the book they reside in and that they are an Agonist: a being made from stray light who was meant to live till their dying days in seclusion. What's strange is that Alex seems to enjoy their isolation, and Alex doesn't seem too keen on relaying their whole life story to anyone.
That is, until a certain reader (or Outsider, as Alex likes to call them) opens the covers of Alex's home.
"...you ruined my perfect streak of isolation."
It doesn't seem too bad. Alex finally has some company.
However, an unwanted visitor seems to creep in the more Alex talks to this reader.
It's only a matter of time before Alex is destroyed completely.
