The party enters the Kyuri Marshlands, having gained Almayce the cleric of Pelor while still adventuring in Algeth Valley. Just as they cross into the Marshlands, they are accosted by a group of Helion Knights, led by Kalden Thentral. He abruptly demands that the party be searched, and only after the party is ready to attack to defend their right to privacy does Marshal Brannoch Dugan (who had been hidden along with his Outrider forces in the nearby marsh grass anticipating Thentral’s demands) step in and rescue the party (recognizing them as the help Brann Delgas has sent) remind Thentral that he has no jurisdiction in the Kyuri Marshlands, and that it is his right to question or search suspected criminals. Thentral is furious, but knows he has no legal ground to stand on, and storms off. The party is sure they have not seen the last of Kalden Thentral.
Marshal Dugan brings the party to Greenwater, the main halfling village in the Kyuri Marshlands. There, he informs the party that the lizardfolk in the area—who had previously been tenuous allies and trading partners, had suddenly turned violent and attacked the halflings on site, even restricting their travel through the marsh.
The party is ambushed by a party of lizardfolk, but they don’t immediately attack; instead, the party is recognized as allies of the halflings, and the group’s marsh mystic, Iztehuacan, asks for the party’s help. He asks them to free his companion Marsh Mystics from some strange mind control being exerted over them, and to identify the source. Iztehuacan suggests they gather berries and herbs in the swamp in order to brew a liquid called Neralac, a vision-inducing compound, as well as a Sporecloud Mushroom; combining the two and letting the liquid ferment in the mushroom should create a grenade-like weapon with which to incapacitate affected Marsh Mystics.
After capturing the first Marsh Mystic, the party discovers an obsidian crystal with glowing green flecks in it embedded within the Marsh Mystic’s chest in an angry wound. They bring the subdued Marsh Mystic back to Iztehuacan, who identifies the crystal as a Felshard, a form of demonic control. He asks the party to bring him two more of his fellow Marsh Mystics, as well as three Atlec pearls so he can perform a cleansing ritual and free his people. The Atlec pearls are found in giant Atlec clams off the coast of hte Kyuri delta, fairly close to The Gloomvale.
The party does so, and in their absence Iztehuacan has scryed for the source of the Felshards—they were implanted in his brothers by sahuagin who serve Sekolah, a powerful devil and the primary deity worshiped by the sahuagin race. After recovering the remaining Felshards and Atlec pearls, Iztehuacan at last asks the party to carry out revenge on behalf of his people.
The party is to locate a small sahuagin scouting party, slay them, and steal their Qalta horn, which can be blown under water and heard by the sahuagin. The party is then to blow the horn to summon Na’ek’agin, the local high priestess of Sekolah in the area, and slay her as revenge for her sleight against the lizardfolk. The party does so, lures Na’ek’agin onto shore, and attacks her, eventually defeating her and her raiding party. As she dies, she tries to warn her remaining brood to return to and protect… something. Unable to finish her thought, she dies at last.
The party investigates a shipwreck the sahuagin had been using as a base, sunk perhaps a decade or two ago, and find a strange treasure chest completely covered with barnacles and limpet. With their arcane knowledge, they discover the chest is opened by blowing bubbles over the spot for the lock, and inside the chest they discover a curious sandstone amulet, perhaps 4 inches across. To most of the party, that is all it appears to be. To Tieran, there is a faint, indistinct marking on it he can’t quite make out. To Isidro, there is a clear iconic eye, and it appears to be made of sapphires embedded within the stone itself. When he shields the stone from the sun with his hand, the iconic eye disappears leaving only the sandstone. The party has not yet found anyone able to identify what the stone is, or why Isidro and Tieran can make out what they can about it.
Sekolah makes an appearance, and though uses no words, is clearly angry with the party, and vows revenge for the death of his priestess.
In the meantime, the undead haunting The Gloomvale have increased, and moan and scream even louder than before—and far off in the distance, a cloaked figure wearing a black cloak passes into the forest as though the undead don’t mind it doing so.
The party returns to Iztehuacan, who is joined now by Marshal Brannoch Dugan, and are asked by both to investigate the Gloomvale. Ri picks up her crockskin clothing custom tailored after fending off the crocs in the swamp while gathering the berries—one skirt, one pair thigh-high boots with stillettos, one pair without.
