SCP-3615 is a stone altar, 9.15 m X 9.15 m X 4.57 m, that dates back to 586 BC.

How did we date it, and why are we using BC instead of BCE?

The artifact is generally consistent in style and construction with contemporary altars,

I would define this a little bit, as to what "Contemporary altars" means

Notably, the structure is covered in a thin layer of feces.

Human feces?

All attempts at removing this coat without damaging the object have failed. SCP-3615 has a constant buildup of static electricity.

I'd reword this a bit. "All attempts to remove the layer of feces without causing significant damage to SCP-XXXX have failed. SCP-XXXX maintains a constant [POLARITY AND CHARGE] level of static elecricity."

Two to three days later, an acid rain shower will manifest over the site of the Type-H Event.

I'd either cut this, or define what you mean by "Acid rain" a bit.

SCP-3615-2 claims claims that its senses are connected to SCP-3615-1's senses, but that they are otherwise unconnected.

You mention -2 before you define it.

Although this procedure calls for the use of human meat, porcine meat can be substituted without consequence.

may be substituted*

No other comments on these.

What is a "contemporary altar"? I'd be more inclined to believe this line of thinking if it were compared to a particular art style/era.

Notably, the structure is covered a thin layer of feces.

ewwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww. Also, if it is in the article, it is notable in of itself.

SCP 3615 has a constant buildup of static electricity.

This line feels tacked on and doesn't really flow well. Not sure how you can move it to fix it, but it doesn't read well.

These flies undergo accelerated development, progressing through their lifecycle within hours.

I'd refer to them as "affected flies".

leading a build up of fly corpses on the object itself, as well as any nearby surfaces.

I assume you meant "leaving".

Flies are anomalously attracted to SCP- 3615.

This, again, feels tacked on, as well as not reading well at the end of the paragraph. It would serve you much better to put this at the beginning, where you describe the effects that this has on flies, first.

Should Procedure NI not be carried out, SCP-3615 will undergo a Type-H Event. In a Type H Event, SCP-3615 will emit an aerosol of fecal matter, ignite, and SCP-3615-1 will soon materialize.

"Should Procedure NI fail to be carried out, SCP-3615 will undergo a Type H Event, emitting an aerosol of fecal matter and ignite. SCP-3615-1 will materialize following this event."

SCP- 3615-2's voice has been described as "hoarse" and "multiple voices speaking in unison".

This comes off as a bit unclinical. Not quite sure how you would fix it, though.

SCP-3615-2 identifies by the mythological epithet "Baal", a name ascribed to multiple deities in the Middle East, spanning from (buncha blackboxes that you have)

Is there a particular reason to censor those? could List like 00 le the name Baal and find out that info. It seems like this is redacted for no reason.

Not much to say, other than that the second interview feels a lot like it is just exposition thrown into the form of dialogue. Granted, it serves its purpose, and would not make it earn a downvote from me, but it does feel kind of…rushed, I'd say. This POI gives away a lot of information very quickly, a lot of very convenient information that the reader might have been asking for. It just feels too easy.

Again, not much to say. This concept is intriguing and very obviously well thought out. I want to pull your attention to one thing:

Refer to Appendix 3615-A for further details.

Ok, where is that? It's completely absent from the document, and I never find out what this Procedure NI is. Leaves me wondering and wanting to know, and not in a good way. It seems like a piece of information that isn't 100% necessary but would definitely add to the article.
