Lisa Wells has just been fired from her job at the library. She's come home to find someone has set her up with a Gmail account and a blog, with several posts already backdated by someone named "Antevorta." "Antevorta" has written telling her to check the black chest in her attic. She doesn't have a chest in her attic...except now she does. An old chest that contains the story of "Elizabeth Wells," an ancestor of Lisa's that lived in the Wild West. Lisa reads the story, until she comes to the end where Elizabeth encounters the Archangel.
And then things take a turn for the weird when a psycho named Grendel attacks Lisa and she is saved by a mysterious woman named I-330.
Mephi is a blog that is a combination of The Slender Man Mythos, The Fear Mythos, and the Cthulhu Mythos. It also contains numerous other references, mainly to Doctor Who and We.
Tropes included in Mephi:
- Action Girl: I-330, and Lisa gradually develops into one.
- Anachronic Order: As a result of the time travel. The blog opens up with two posts from much later in the story, then goes into the past, then returns to the present and remains (mostly) chronological for a while. Then everything gets crazy again when past I-330 and future I-330 start posting about their adventures at the same time.
- Ancient Conspiracy: The Noctis Custodes.
- Anyone Can Die: And they will. The only Fear Mythos story with a higher named character body count is OH GOD THE RAPTURE IS BURNING.
- Apocalypse How: Class X-5, with the threat of Class Z.
- Ax-Crazy: Grendel can get like this.
- Badass Normal: Lisa slowly becomes this, especially after she sprayed the Intrusion with a flame thrower.
- Buffy Speak: Occasionally, I-330 will delve into this. See: "Eldritch shit and nonsense."
- Changed My Jumper: Occasionally Lampshaded, but no matter how often I-330 complains about having to deal with the confusion from her anachronic attire, she always dresses like the 10th Doctor.
- Cerebus Syndrome: While never very light hearted, the story does slowly become darker, as the threat escalates from a simple evil CIA conspiracy to the end of all reality.
- Combat Tentacles: Several eldritch beings, as well as I-330's shadow arm.
- Crossover: While this is already technically a crossover between the Fear Mythos, the Slender Man Mythos, and the Cthulhu Mythos, this post also establishes that the "Noctis Custodes" (from the Slenderblog It's all David's fault) also exists.
- Cutting the Knot: Locked doors are for people who can't teleport.
- Elaborate Underground Base: The CIA's built a few of these for the purpose of fighting/studying the Fears.
- Did You Just Index Cthulhu?: Oh yes.
- Did You Just Punch Out Cthulhu?: Being a Fear or an Outer God does not save one from Anyone Can Die in this story.
- Did We Just Have Tea with Cthulhu?: In its interactions with I-330, EAT has often been extremely helpful and polite. At least, so long as they share the same goals.
- Did You Just Flip Off Cthulhu?: I-330 gets a lot of amusement from taunting the Fears.
- Did You Just Romance Cthulhu?: Considering I-330 is essentially Nyarlathotep, the relationship between her and Lisa can be seen this way.
- The Drag-Along: Lisa, at the start. She eventually grows into the adventuring lifestyle.
- Evil Only Has to Win Once: Mentioned by EAT when discussing Grendel's plans for revolution against the Fears. If Grendel's revolution succeeds in just one universe, the entire multiverse is destroyed.
- Eyepatch of Power: I-330 has one.
- Eye Scream: How I-330 gets that eyepatch.
- Genre-Busting: Does this to the normal Slenderblog or Fearblog.
- Glowing Eyes of Doom: Grendel, and I-330 when she's tapping into her more eldritch powers.
- Half-Human Hybrid: I-330 and Grendel.
- Government Conspiracy: Several branches of the government have created several secret groups dedicated to dealing with the Fears. They don't get along very well.
- Humanoid Abomination: Grendel, as well as I-330.
- Humans Are Bastards: Invoked by EAT.EAT: "...the Wooden Girl has ‘gone native’ and seems to find amusement in imitating humans, even if it means forcing herself to act based on temporal cause and effect."I-330: "Imitating humans…? I saw it rip off a man’s arm while laughing!"EAT: "Indeed. Her imitation is frighteningly accurate."
- My Future Self and Me: I-330's from different points in her life have occasionally interacted with each other. And argued in the comments section of the blog.
- The Old Gods: The multiverse used to be ruled by the Cthulhu Mythos, until the Slender Man overthrew them and the Fears rose in their place.
- Power Makes Your Voice Deep: When I-330 draws on Nyarlathotep's powers.
- Prophecy Twist: Everyone assumes that the "suited demon" referred to in a summoning ritual is the Slender Man. No one stops to point out that I-330 is always wearing a suit.
- Screw Yourself: Lisa maybe would have been a bit more hesitant to start a relationship if I-330 if she knew the latter was her future self....
- Sealed Evil in a Can: The various gods and monsters from the Cthulhu Mythos.
- Shout-Out:
- The name "Mephi" and I-330 both come from the dystopian novel We. Every character name is also a reference, including "Lupine Wonse."
- There's also characters named Roy Makhno and Lucy Parsons, for some historical references.
- One post by Grendel consists entirely of "it hurts it hurts it hurts it hurts it hurts it hurts it hurts it hurts it hurts."
- There are numerous references to the Cthulhu Mythos, including the characters traveling to Miskatonic University.
- The facility I-330 briefly ends up in is the SCP Foundation in all but name.
- Steampunk: What Elizabeth Well's written adventures eventually become.
- Teleport Spam: A favorite tactic of the story's time travelers.
- Timey-Wimey Ball: Even quotes the Trope Namer.
- Tomato in the Mirror: I-330 is Nyarlathotep merged with Lisa.
