Rockspike Archipelago

We were traveling in two small boats, Silk and I in the newer one, Tiglath and Tumlak in the dilapidated one.
Yet we were the ones who crashed into that cursed rock. We were thrown into the water, but luckily, a small beach allowed us to quickly escape.
Our companions had to come to our aid, and just as we were about to board their boat... that hideous creature emerged from the water.
