CREATURE 14Male sedacthy cult leader
High-ranking sedacthies are expected to both plan campaigns and wade into battle. These speakers achieve their rank by accumulating several large servants or a single massive creature like a megalodon.
Sedacthies are amphibious, fish-like humanoids who lurk in Golarion's oceans and are known for leading their animal servants ashore to devour air breathers. When an entire fishing village disappears overnight, sedacthies are the first suspects. Sedacthies pride themselves as natural leaders, with ambition limited only by their strict adherence to hierarchy. A sedacthy's station is determined by the strength of the animal servants they press into service, and the mettle they prove during hunts and in battles against outsiders.
A sedacthy speaking Thalassic can be understood by any animal that has a swim Speed or the amphibious or aquatic trait. By spending a week regularly interacting with such an animal, the sedacthy can make it permanently helpful.
This sense allows a monster to feel vibrations caused by movement through a liquid. It's an imprecise sense with a limited range (listed in the ability). Wavesense functions only if monster and the subject are in the same body of liquid, and only if the subject is moving through the liquid.
