Frantic Bay

Areas
The basis camp is on the beach where a narrow way leads to area 1 and a climb way to area 6. The areas 1-4 are flooded land areas (like area 1 of the Flooded Forest or area 9 of the Deserted Island). The land is covered by slick in where a special Fish monster hides, the Hellfish. To get to the areas 5-7 you need to climb because they're are on the rock formations that is around the bay. There you are on a rock landscape often inhabited by different herbivores and by water living wyverns, mostly birdwyverns that brood there. Area 8 is a cave that you only can reach to when you climb from 7 down (one-way). To get out you need to jump down to area 3. The areas 9-11 are in the ocean with vast room where you can see often big Fishes and Leviathans. The top predators are on land the Mud Leviathan, in water the Dunkleosteus.
