On the seaside of the Bison Mountain Range, countless towering giant redwoods seemed to pierce into the clouds.
These trees, with an average height of over a hundred meters and unbelievably tough, acted as natural battleship skeletons, and any redwood over one hundred and fifty years old, whether magical or not, was considered equivalent to Sublimation Plants. The network formed by hundreds or thousands of these giants could even constitute a natural Spirit Energy Field with a vague collective consciousness of the trees.
When the pioneers of The Empire first reached the Southern Sea's Redwood Forest, they were overjoyed, believing they had found an excellent natural warship base and thus established the precursor to Harrison Port.
