The backstory to Eye of the Crocodile King involves a journeyman academic named Maren Fuln who works at the Arcanamirium (a prestigious school of magic) in Absalom. A week before the game starts, Fuln found an old amulet in storage and put it on, not knowing that it contained the soul of Lord Corgan--a docent of the school fifty years ago who was executed (with his soul to be forever trapped in the amulet) for involvement in foul necromancy! The soul of Lord Corgan started influencing Fuln and led him to step up experiments on some sort of man-crocodile aberration. After a lab explosion, Fuln was knocked unconscious, his experiment escaped, and the amulet was found by a dim-witted animal handler named Lemedor. Lord Corgan's soul exercised control over Lemedor and drove him deep into the sewers underneath the city. There, Lord Corgan has taken over the experiment and taken physical form as a sort of vicious reptile-man (think Killer Croc or perhaps the Lizard) and is planning to organise an army of troglodytes to wreak havoc on the Arcanamirum. For his part, Fuln realises he needs help and calls an old friend, Venture-Captain Adril Hestram.
This is where the PCs come in. In a surprisingly curt "briefing", Hestram quickly summarises the gist of this background and sends the Pathfinders to the Arcanamirium to meet with Fuln. Fuln is in a big hurry to get the amulet back, but also terrified of the sewers--there's no way he'll go himself. The scenario has a good list of Q&As that might arise when the PCs interact with him, and I like how he's written (and it's cool to see he appears in a couple of subsequent PFS scenarios in later seasons).
The rest of the scenario takes place in the sewers, a favourite setting for writers in Season Zero. It's essentially combat-combat-combat from this point on, though there is a chance for a little role-playing. Depending on the group, this could be a very fast scenario to run through.
The first encounter takes place when a troglodyte in Lord Corgan's employ activates a simple but effective trap: knocking over a big box of rats! Rat swarms can be dangerous for unprepared low-level PCs, but the scenario does provide the GM with an out here as Fuln might just poke his head into the grate and use his wand of burning hands. Still, it could be a bracing start!
The second encounter involves a wounded otyugh sitting atop a pile of trash. Some of the faction missions require PCs to trawl through the trash after the battle, which is exceedingly unpleasant to imagine.
Next up is an ambush by a couple of troglodytes and Lemedor (the mind-controlled dim-witted animal handler from the surface). It's a decent challenge for an average group. The good news is that Lemedor, once he shakes off Lord Corgan's mental domination, is happy to talk and can fill the PCs in on the villain's plans. The bad news is that Lemedor only shakes it off if he's "staggered", which means getting him to exactly zero hit points (or knocking him out and healing him back to consciousness, I guess). When I ran this, he got knocked down and stayed down.
The penultimate encounter is versus (at low-tier, at least) a crocodile and three more troglodytes. Crocs can be fairly deadly, and I think most groups are going to be fairly worn down and low on resources at this point.
Now we get to "Lord Corgan the Crocodile King"! I think the concept is fun. Assuming the PCs can defeat him in his lair, they can . . . extract (yuck) the amulet that is inside him.
A brief conclusion has an ecstatic Maren Fuln offer to always be available if the Pathfinder Society needs his aid (represented by a boon on the Chronicle sheet).
I don't read other reviews before writing mine, so I'm not 100% sure why this scenario was retired. There's no objectionable content or plot discrepancies, and I don't think any single encounter is crazy-hard. My best guess is that the cumulative effect of the encounters may have led to a lot of TPKs. There were no casualties when I ran the game, though it got very close in that last battle. In my mind, Eye of the Crocodile King is perfectly playable with just a nip and tuck of (for example) a troglodyte here and there. It's not a great or memorable scenario (and the idea of someone accidentally freeing the trapped soul of an ancient threat is pretty cliched in fiction), but it's an average representation of what Season 0 has to offer.
