i started building a tree house walkway in the swamps, using the iron in the swamp to make wood iron poles to support the large distance between the trees. the big swamp trees are unbreakable and count as "grounded" for building.

in every seed i sail around the edge of the world looking for outcroppings of land that are close to the edge so i can build a lookout as close as possible, with the goal of looking over the edge.
