I was expecting something like Paizo's standard Pathfinder Society adventure writeups, which present specific context for the setting, a mildly interesting quest-giver, some other hook, and a statement of the expected party level (not just on the product's Web page). Instead, we get some phrasing that seems both vague and awkward. For instance, before the quest begins there's this description of what you did after it:

"Damage to the site is to be avoided at all costs, though any trinkets you spotted in the course of clearing it out was yours to have. If you claim something and don’t want it, they will pay top rate (55% instead of 50% of market value) for, provided it came from this place in particular." (sic)

The premise of the adventure is that the PCs have been hired to clear out a probably-dangerous dig site for archeologists. How was this site found? Passive voice just says it "was thought to be a gentle hill", so there's no interesting backstory. Who's hiring the PCs? It's "the hirers", so there's no Paizo-style cue to help set the scene. Late in the adventure there is a named NPC who was one of these employers the PCs might've met, so if I were running this I'd revise it to present her in scene one to give the players a named contact with a personality of sorts.

It's also odd that these archeologists don't care if the PCs loot the place for valuables, which seems like it defeats the purpose. The oddity could've been fixed with some talk about "you can keep stuff after you let us examine everything you found!" All the more reason to give us an NPC for the players to talk to.

The PCs get attacked by bandits, who have claw attacks despite being ponies and not having any claw-like weapons. Are they connected to the endgame? I have no idea from reading the adventure. If they are, I don't see how, and if not, what are they doing there? When did they show up? It's a missed roleplaying opportunity that could involve bluffing and backstabbing, if given an explanation.

I feel this adventure needed another round of proofreading and some rethinking of its logic. Some of these problems would be simple to fix.

The positive aspects? It's nice to see Ponyfinder content. I do like that there's a special rule in play here (trying to limit collateral damage) and an encounter with something probably non-hostile. There's an event at the end that presumably leads to other adventures, though we're not given adventure seeds for what those might be and it says something about Everglow's history that may make players say "wait, this is canon?" You may find that good or bad.
