Treetop is the Age which will grant you access to Odema. It's fairly small, consisting mainly of an explorable treehouse, perched on the end of a tall cut tree, which protrudes over the edge of a cliff.

Basic gameplay:
You link in in a forest at the end of a catwalk, high up among coniferous trees. It is mid-day and very sunny. Walking forwards brings you to a fork. The only path forwards leads to a clearing of sorts, where the cabin presides. The other path to your right goes back into the woods where a Nexus book can be found.
The clearing is at the edge of the woods and holds the treehouse, which stands on the cliff's very edge, erect over the precipice, having been built on a tall tree marking the end of the little wood. A bridge leads to a landing built onto an adjacent tree, which connects the said bridge with a wooden suspension bridge leading to the cabin's front door.
A lookout point can be reached via a trap door in the cabin, beneath a rug. The lookout point consists of the 5 wooden pylons holding the cabin up and serving as a makeshift frame and as seats , a thatched floor connecting all, and a little round table where a small telescope on a tripod rests. The view from here is dazzling - a rich forested landscape hosting a range of medium sized mountains all covered in greenery, a bright blue sky dotted with clouds, sunlight of an incredible vividness and peacefulness.
In the cabin there is a bed and two desks. The desk near the exit holds a plate, sitting in it, a forgotten meal of Odema shrooms. The desk on the opposite wall holds the Odema book. The bed has two drawers - one which contains a necessary key. The key is what must be used to open the Odema Willow hut.
