After finally getting the hang of building bio-domes, I decided to add a few more to the glacier seed and connect the domes with a railway system.

You will find a few scattered treasure chests in the domes, nothing too fancy though.

A small floating castle, a vantage point, a tree house, a deserted fort and an underwater mine can also be found along the minecart track. (The fort is a bit further to the east.)

There is a second minecart track near the floating castle that will lead you right to the fort. (Follow the stone poles with the torches.)

As always, the original landscape has mostly remained untouched, so change and undo whatever you like.

Happy building!

This is an exact replica of the real CN Tower. I hope you enjoy :)
