Mare Internum is a SciFi webcomic by Der-shing Helmer, author of The Meek. The story kicks off in a research station on Mars, during the early days of colonisation, and Dr. Mike Fisher has just been fired and is due back on Earth. Hes not very happy about it.
As of this writing, the comic hasnt updated since Dec 2018. Start reading here.
- Beneath the Earth: Most of the story is set in a complex system of partly flooded caverns beneath Mars' surface, which are still inhabited by a variety of Martian organisms and Organic Technology.
- Bilingual Bonus: Mare Internum is Latin for "Internal sea." This turns out to be a subtle use of foreshadowing.
- Body Horror: First, Mike gets a compound fracture to his femur. Then said femur gets some weird parasitic growth that appears to have a mind of its own, and then there's something on Mike's face... something that seems to be living, and stuck. Downplayed later on when it turns out that these turn out to be largely beneficent changes — the thing in his leg, for instance, helps him breathe underwater while acting as an organic split for his broken leg — but it doesn't detract from the underling sight of a flower-like fleshy growth spiraling from his leg while shelf fungi cover half his face.
- Driven to Suicide: Mike. He states how he wants to have control over his life and die on his own terms. His attempts to die keep failing however.
- Evil Uncle: Mike's uncle Brian sexually abused him when he was younger.
- Goodbye, Cruel World!: Mike's suicide is delayed when his "Bye" note flops over.
- First Contact: Mike runs into an intelligent Martian named Kallakore, who had been living under Mars's surface.
- Interplanetary Voyage: The trip back to Earth takes six months, which is about what it would take in the present day.
- Interrupted Suicide: An urgent, automatic comm call cuts in on the suicide, but the caller remains oblivious throughout.
- The Mentally Disturbed: Mike clearly has quite a few mental issues, which eventually caused him to be fired from the expedition, and the comic opens on him trying to hang himself. It just gets worse from there.
- Mohs Scale of Science Fiction Hardness: Somewhere between type 4 and type 5.
- Starts out as a pretty hard type 5. The technology on the research station could all conceivably exist based on our current technology, and the depiction of Mars is based on what modern science tells us about the planet. LEVi might stretch the limits of what we know our current tech can do, depending on how advanced his AI was, (although his levitation capability is unexplained) that's about it. In some respects, this remains the case; the temperature, atmosphere and water in the cavern are subsequently attributed to geothermal vents, for example, so the jury's still out on this one.
- Then life and the survivor of an ancient advanced civilization is discovered beneath the surface. The existence of the advanced aliens and their Organic Technology (which can keep them in stasis for billions of years, and allow Mike to breath their atmosphere, among other things) could push the comic into One Big Lie territory
- No Biochemical Barriers: It appears this way at first when some kind of Martian fungus attaches itself to Mike. See Body Horror above. Later justified when we find out that life on Earth evolved from Martian waste.
- Once-Green Mars: Mars used to have life on its surface billions of years ago, as well as an advanced alien civilization.
- Organic Technology: The basis for the ancient Martian civilization. It currently exists as/maintains a pocket of life under the martian surface. At first glance it is indistinguishable from a naturally evolved ecosystem or organism. Mike has one growing on him that allows him to breath the atmosphere and to respire underwater; Kalla describes this as about as disturbing as seeing someone with "a toaster fused to their face".
- Parental Abandonment: It is revealed Bex is part of the "First Wave Initiative", meaning she is a permanent colonist on Mars. This is in spite of the fact that she has a husband and young children back on Earth. Mike calls her out on this during his Freak Out.
- Parental Neglect: Flashbacks reveal that Mike's parents were self-absorbed jerkasses who were more focused on the drama surrounding their impending divorce than taking care of their son and were totally oblivious to the fact that Mike's uncle was sexually abusing him.
- Reduced to Ratburgers: Bex is on Mars to set up alternative food sources, with a focus on "entomological subsistence". Insect diets have been proposed repeatedly in our time, but judging by reactions here they still haven't quite caught on.
- Super Not-Drowning Skills: Mike's parasites allow him to breath underwater somehow. It looks like inhaling water is still unpleasant for him however.
- Wham Line: From Mike signalling the beginning of his Freak Out:Bex: I'm... I'm sure they'll find your LEVi, one day.
Mike: I doubt it. I hid him down deep.
- What the Hell, Hero?:
- Mike rather cruelly rips into Bex when he finds out she left her family on Earth to become a permanent colonist on Mars. His treatment towards Bex doesn't improve one bit as the two reunite after a caving accident, mainly due to Mike stumbling across Bex having killed his friend Kallakore in a desperation for food.
- Bex, after tbe events where Kallakore returns to life, Mike and Bex reunite, and the Processor attacks Mike and her, finally has enough of Mike's critical behaviour and calls him out, forcing Mike to rethink his stance on Bex.
