Settings
A small dive equipment warehouse near the coast, late afternoon.
Rows of oxygen tanks line the walls. Coils of rope hang from metal hooks. Maps of cave systems are spread across a cluttered workbench. The scent of saltwater and machine oil fills the air. Sunlight streams through dusty windows while the distant sound of waves crashes outside.
Jack is checking his diving gear when he receives a call about a newly discovered cave system. The quiet warehouse contrasts with the dangerous expedition he's about to accept, emphasizing his calm confidence before heading into the unknown.
This setting works well because it reflects his profession as a cave diver and explorer while showing that taking risky jobs is a normal part of his life.
