Solving the problem with the coastal town was quite challenging and took some time. Samiel and the rest of his group discovered that the water had experienced contamination due to a strange eruption on the ocean floor.
From what they could deduce, some bottom-dwelling crustaceans had been driven mad by the darkness lingering in the ocean. Consequently, they decided to burrow into the ground. This led to the exposure of a vein of poisonous minerals.
The problem did not dwell in only neutralising the poison, but also sealing the damage.
Fortunately, between the skills of Samiel and Virgil and Abaddon's raw power, the water was restored. The merpeople were thankful to the group to the point of tears. After a long talk, Govad convinced them to consider using some modern amenities.
