Rattlesnake Island
Two-hundred acres of Florida swampland that is technically part of Matanzas State Forest on the Mainland, Rattlesnake Island is named for the plethora of snake-life (rattle- and not). And is uninhabited since the 1900s, when its one resident died off.
Now the island is more of a curiosity than anything else, though alchemists who wish to acquire venom or other ingedients here might do so at -1 Difficulty to scrounging tests.
Vampires trapped on Rattlesnake Island have almost nowhere to hide, unless perhaps they can bury themselves in the deep swamp, or find the old Rattlesnake Hovel, which - legend has it - is haunted.
