You get everyone safely to the top of the short drop off, but it takes valuable time. Five minutes or more have passed by the time you, Etag, and the 11 gnomes are at the tope.
You continue down the cave. Here, after reaching the top of the short drop off, the land is much wider, about 50 feet wide. It slopes gently down and to the right. You feel almost like you are spiraling slowly back down.
The waterway is becoming more narrow and running faster. You can see the end of the cave about 50 yards ahead. There is a flat area of land where it looks like the giants dock their rafts where the rock becomes flush with the water.
But just a few yards past that, the water flies out over cliff.
You continue going as fast as possible, knowing the giants can't be too far behind, and you reach the mouth of the cave. It is a full 50 feet high and 100 feet wide at the base, like an archway leading you to natural light.
Standing at the edge of the cliff, you see the sky in for what seems the first time in days. Clouds move languidly across. There is no sign of any borken planets or imminent destruction. It is quite beautiful. But looking down, you see the cliff face goes down past where your eyes can see. In fact, there are clouds below you, and you realize you must be thousands of feet high. The giants appear to use handholds, but that would be far too dangerous for you.
To your adjusting eyes, the landscape outside appears to be nothing but mountain peaks, one after another, like giant stalactites reaching toward the sky.
And between the place you stand and the next mountain stretches an old bridge. The bridge is at least 1000 feet across where it connects to the next mountain opening. The gnome-hewn bridge is made of ancient rope and wooden planks, and is perhaps 3 feet wide. Many of the wooden planks have broken off over the years-- over hundreds of years, by the looks of it. The bridge can still hold weight, but it dips in the center (about 500 feet out) at least 20 feet lower than where you stand, before climbing back up to the next mountain cave.
Imagine something like this, but 1000 feet in length and between two caves thousands of feet above the ground:
Etag falls to one knee. You see he is still weak from his injuries being tied to the mast, but you also see that his fingers and hand have become very dark with congealed blood, and his lips are swollen. "I haven't much time," he says. "The Black Curse is upon me. Quickly, get the gnomes across."
OOC:
Giants: Since you do not know how long until the giants get here, it will be rolled by wandering monster rolls.
Rope Bridge: The Bridge will take some time to cross. The key concern is how much weight it can hold. Your XP will be based on getting across, but also based on how many gnomes you safely get across. Too many on there at once creates a compounded danger, both of the bridge snapping (and losing them all) and of the vibrations in the rope that will throw them off balance one at a time.
(If the bridge breaks by weight, it will result in the bottom ropes giving out, and then you will be forced to shimmy across on the upper ropes. The upper ropes will hold everyone's weight, as they are thicker and less worn than the bottom ones.)
Etag: Getting Etag safely across is also critical to get important campaign information and clues, and for other reasons.
