Oh my! That is certainly suspicious. If Vex were to exert some effort in following where the "path" of dead fish leads in either direction..

• what would she find around the hunting grounds? Specifically, using her ranger training, would she notice anything unusual about the location aside from dead fish and dead coral?

• If she enlisted a couple of friends to accompany her, how far towards the palace would the trail take her?

• Is there anything unusual to be found along the route, perhaps an often used stopping point, or items left behind by whatever's leaving this trail?
