I've always wanted to do a Dawn Treaderesque campaign with pcs hopping from fantastic island to island. Ilha de Queimada Grande off the coast of Brazil would be the model for one of them:
"Researchers estimate that on the island live between one and five snakes per square meter."I think there would have to be something astoundingly valuable on that island to get the players to brave the snakes.
"The lancehead genus of snakes is responsible for 90% of Brazilian snakebite-related fatalities. The golden lanceheads that occupy Snake Island grow to well over half a meter long, and they possess a powerful fast-acting poison that melts the flesh around their bites."
ps: What's with Brazil!? First a fire tornado then an island of deadly snakes that I've read about today. They need to channel the tornado towards the island, haha.
