An interesting part is the 90-minute window illuminating beyond the town, but how little it imprints on people's day-to-day activities is a bit of a missed opportunity. Like wouldn't there be some found media where it's documented in newspaper or even graffiti? Hell it can be suggested indirectly LO-556 is a product of that, but it just stops at their comment on "abnormal activities". The reasoning behind the invisibility property was interesting too but I can't pretend I understand how it works beyond the ocular blind-spot reasoning, which I doubt I would be alone on that as it stands. Also the last part elaborating on gualichu is all tell no show, perhaps you could tie it to people's interpretation of said abnormal activities?
One thing I wish it focuses on is its contexts, which it heavily relies on but never substantiate. For starters a basic description of Villanueva, suburbs surrounded by expansive farming land. It would give perspective how tall a 23 floor dwarves its surrounding, especially by the waxing phase. Having to look through Google Earth of all places was inconvenient to put that image together, cause immediately before challenging this assumption I imagined it as some commercial zone where a high rise building is expected.
Also I read the city suffered a paramilitary assassination of 11 people in December 8, 1998, using the firework celebration to conceal the shooting, which begs the question if the anomaly could have had any influence on the matter. Of course if there isn't a tasteful way to expand on this in mind it's best avoided.
Lastly a few nitpicks:
- Wouldn't it rather suggest a psychotronic effect with the current properties instead of generally psychological?
- I suggest you change gualicho to gualichu, as the former brings up a lot more articles about a dinosaur rather than the spirit.
- Lastly update the classification as the icon's still Omega-White. I assume it's a placeholder but it still kept me questioning if it is Gamma-Yellow or not.
I suppose the point is a demon spreading its influence upon a town detached from watchful eyes, but even that is lacking with the objects and music behind the blazing epicenter barely tying in to the rest of the narrative, so instead it feels unfinished delivering on much at all. Funnily enough, it positively reminded me of a NoMeansNo song, with some of its lyrics having a vague resemblance in concept.
