The Order of the Green Vial - Resolved

On one of their return trips from Port Oruss, the party encountered a wagon led by a charismatic green-haired wood elf named Brevelor. His green-painted wagon was pulled by a pair of strange creatures called Lunar Elk who were cared for by a Yuan-ti warrior. In the wagon was another Yuan-ti woman who was revealed to be an alchemist. A pair of humans were camped with the group and the party recognized them as some local scavengers they had encountered before. The men seemed heavily drugged and after they were cured by Sora, a tense exchange took place where the party learned that they had been the victims of the Slaad plaguing the area. Brevelor and the wagon, headed north and bypassing Raven's Crest entirely on their mission to seek out herbs and other resources.
Many weeks later, the party spotted an injured man fleeing from a dark-clad figure. After they intervened, they found Sebastian Blackcoat, Trevor's older brother trying to hunt down and kill Brevelor (See Hunt for the Elder Blackcoat ). The wood elf said that he fled from the order he served after discovering the horrible plans they had for the village of Silverleaf, far to the north. Now he is asking for help to stop the Order of the Green Vial.
The leader of the group, a Yuan-ti Abomination named Ockoa is enslaving and converting the gnomes of Silverleaf into his slaves and Brevelor thinks that he is planning something much worse for the coming Spring equinox. Other members of the order include, Calaea, the alchemist that was travelling in Brevelor's wagon and Riskaris, a green dragonkin arcanist.
After traveling via the Sable Drake, the party approached Silverleaf Village and encouted a scouting party made up of elves and yuan-ti. After dispatching them, they reached the village and were spotted by a keen-eyed sniper who Trevor recognized as the same hobgoblin he squared off with at the museum in Port Oruss. After a long and brutal battle, the party defeated the order, leaving most of their number dead except Ockoa, who escaped using the magic of the Coin of the Dark King that he carries. The elk-handler, Saelvas surrended to the party and agreed to go back home, taking the last survivors with him.
The party took the gnomes who were partially transformed into Yuan-ti back to Raven's Crest for treatment along wiith the grand-daughter of the village elder.
