In 3841 AR, the druids of the Wildwood Lodge approached the emperor of Taldor with the request to give them the autonomy to protect the Verduran Forest, which is the last dominion of the blackwood trees. In exchange, the druids would ensure that Taldor would get wood for its ships for the duration of the empire. The emperor agreed as he was tired of losing men to fey raids and unable to control the forest anyway. The treaty signed is called the Treaty of the Wildwood. The outcome was that the eastern part of the Verduran Forest, within Taldor's borders, became a semi-autonomous prefecture of the Taldan empire.
Once per year, Cassomir sends a diplomatic delegation to the Isle of Arenway, to reaffirm Taldor's peace treaty with the druids. In the ceremony, the diplomat stands in front of a senior druid, and exchanges a bag of seeds for a small piece of fine wood. Then the diplomat sails downriver back to the city. Many captains consider this piece of wood especially lucky, purchase it from the city officials, and usually carve the wood to make a figurine of their ships.
