Risk loosing control over your spell, open the breach even further
From Create Your Own Story
You decide to take a few risks. You link your breach to the seas beneath the moon of Titan, and decide to stretch it a bit. It is then that you realize what will happen. You are about to drown this city, and yourself. You frantically try to pull the breach shut, but it is too late. It opens by its own will.
You do the first sensible thing you've done all day. You pull your window shut and ward it from damage. This entire city will be under a hundred meters of water soon enough, at your rough estimate. So you rush through your home, warding every entrance and exit. You should be safe, for now. But then another pressing matter comes to mind. Oxygen. You've got a few days' worth, now that you've sealed every possible escape route.
Perhaps the breach will seal naturally in time. But no. You look down from the top floor window, and the sea is only a few meters below. Your porch and second floor are completely submerged.
You take a risk and probe the waters with a simple spell. And yes, your worst fears are realized. Every major body of water in this solar system is stretching the portal. What do you do?
