Energy harpoons and related legendary weapons like Ahab’s Crosshairs are another story altogether.

I’m pretty sure that seadwellers are the only ones who know how to manufacture them and/or find them, and it’s the main weapon they use to keep the land dwelling castes in check. I’m not sure how many people have seen Slumdog Millionaire, but there’s scenes early on where a child obtains a gun and is suddenly able to manipulate adults into doing essentially whatever he wants, and I think getting your hands on an energy gun, as a land dweller, would be similar to that; an energy gun can kill anybody, no matter how physically strong, so if you manage to pick one up from a seadweller, you’re king in the land dweller world.

Until the sea dweller authorities get you, at least. So you’re probably most likely going to keep it a secret at times when it isn’t necessary to show your full power.
