Some ideas for the DM with players starting off to explore Jeremy Strandberg's wonderful Sapphire Islands Campaign Starter: https://goo.gl/W21vD5
Maybe the Island of the Lizard God is around here somewhere?: http://beholderpie.blogspot.com/2014/04/island-of-lizard-god.html
It has plenty of monsters: https://drive.google.com/file/d/0B_z2jviQ47OqUlRYczliLTFpclk/edit?usp=sharing

I know that my Temple of the Shark God has surfaced somewhere nearby: https://drive.google.com/file/d/0B7cav44145d9RXRZZHBMQ2RIeGc/view?usp=sharing
and isn't the Island of the Apes https://drive.google.com/file/d/0B7cav44145d9bWRSd2o1eG1rTXM/view?usp=sharing also in the general vicinity?
Isn't the Tomb of the Pirate Priest also around there somewhere? https://drive.google.com/file/d/0B_dDnQ_810l9VFpkWjEtaEJyc2M/view?usp=sharing
