The Treasure of Syreni
Everyone loves a pirate party, we are just adding in scuba diving, mermaids, a flooded quarry and treasure offering eternal life and power with it
Navigation and buoyancy is key for this, yours might be on point but what about your ship mates??
It won't be an easy quest, legend has it that the treasure is guarded by the mermaids of Syreni and won't let it go without a fight.
