The entire Rex County is situated on a high plateau where the temperature is much lower than that of the southeast regions of the Wood Dynasty. Many regions here maintain their pristine state due to the scarcity of inhabitants. Shrubs and tundra abound, with forests scattered all over. The trees, firm and tall, have been growing for countless years. They serve as excellent construction material.
Experienced locals can identify certain signs on the tree bark on the sunny side of a tree and judge whether there is any Blood Condensation on the roots.
Owen Bertram had come across some written records about these "signs" in the Horizon Bureau's documents. Allegedly, the local Horizon Bureau officials had interrogated the native people to find this information. He took interest in examining a few huge trees but to no avail. As a last resort, he exerted his spiritual sense, but still found nothing on the roots.
