The Cave Under the Tower

[FantasyMaps]

There is almost a zero percent chance that after visiting the cliffside beach adventurers are not going to explore the tower at the top.

Underneath a wooden cellar door a cave awaits. The left, descending path leads to an underground body of water within a bioluminescent room. At the tail end of which a secret chamber requires the party to dive into the lake to find the entrance.

The right, ascending path leads to another exit into the ruins atop the cliff, which is going to be my next map!
