Take your favorite route back to the fourth island you visited, the one with the underwater throne where you summoned the whark. (You can get there by taking the mag-lev in the “basement” of the fish totem in the forest, or you can get there from the back entrance of the house on Boiler Island with Gehn’s laboratory in it.) If you take the fish-totem route, once you have taken the mag-lev and are on the fourth island, make your way to the elevator. Take it up, and then follow the passage to where the other mag-lev awaits. (If you took the Boiler Island route, you are already at the correct mag-lev.)

You can exit this mag-lev either of two ways, by rotating the mag-lev using the lever inside of it. One of the two exits leads to a metal staircase that heads up to the surface of this island.

Follow the jagged pathway towards the large fortress ahead of you. There are plenty of whark tusks around, thus the name of this island. You will see glowing liquid below at one point, and you will pass several interesting rock formations. Perhaps you can get a better look from above. At the end of the path is an elevator. Enter, and ride the elevator up to the top story of the fortress. Get off, and head forward to where you have a view of four islands. There’s also a bronze map with some shapes on it, and if you look below, you’ll see what looks like a large-scale map of some islands. Hmm… wonder which islands those represent?

Press a shape on the metal map, and watch what happens. Press a few, even. Can you figure out what’s going on here?

After trying everything, and meditating over the view, turn around and head back towards the elevator. Proceed into the building, and then continue straight towards a lagoon. For now, ignore the building before you. Take a right, and follow the pathway until it ends. You have a view of yet ANOTHER dome, and your handy viewer will probably stop it, just like the others. Unfortunately, this one looks like it got sat on by Fat Albert. When you stop it, you may have trouble catching a glimpse of the symbol when it stops.

If you’d like, you can go check out the dome you just stopped. If not, take the path back to the entrance of the floating building in the lagoon, and go inside. There’s an interesting device in the center of that floating room, which looks like a bunch of spikes in a grid, with a smaller grid next to it with glowing square shapes on it. Press a square on the small map, and you get spikes popping up in the big map that form some topographical shape.

Time to put on your thinking cap. The shape in the small map is the same as the one you pressed on the metal map overlooking the large-scale island model outside! And each of the five shapes you see here (and that you saw way back in the large gold dome, on that small schematic map) represents one of the islands in this game! Take the time to run back and forth between the large-scale model of the islands and this topographical map-making machine, and figure out which island is which. It takes some time to put two and two and two together, but eventually, you will realize through trial and error that the spikes that pop up when you push a square represent the shapes of landmasses of that particular island.

You need to figure out what you’re looking for on these topographical maps. If you look carefully, one aspect should stand out on each island. Start with the smallest one, perhaps, the one-square island, and see what leaps out at you.

That’s right, it’s the small dome that’s on each island. That’s what all five islands have in common. You need to make a map of each island, and figure out the exact coordinates of the dome on each island, according to the grids. You may need to return to this machine later if you are unclear on the concept, or if you don’t get your coordinates exactly right for each dome.

Once you’ve done your best to nail down the coordinates of all five small domes, it’s time to head back to the first island and climb to the roof of the Big Gold Dome. Take whatever route you please, and we’ll meet you on top.
