The Druids, for their part, were the first to understand the value of self-reliance, and they adopted the idea of a "non-human" as a way to honor their ancestors. In the first century after the coming of the Druids, the road system was expanded to include the entire country, which was a boon for farmers and travelers alike. The Druids also developed a system of magical signaling that would allow them to track down travelers who were lost. For example, if a person was lost by a lost thread, Druids would turn a wheel of fine silvery metal and announce that the traveler had been lost. If no one was found, the wheel would turn, and the Druids would announce that the person had been found. This method of signaling was so effective that it became the Druids' trademark.
The Druids were not the only ones who came up with this system of communication. The roads themselves were also a source of prestige, as the king's people were the first to build them. In the first centuries of the reign of Ba'al, the road from Ba'al's capital of Tarka to Khotan was the only real way to travel between the two cities. In the 16th century, the king invested heavily in a network of roads linking the two cities. In the 17th century, highways were built between the two cities, and at the end of the 18th century, roads were built between the two cities. In the 20th century, the Chinese built the first highways in the world that bypassed the kingdom of Ba'al. The Chinese began building the first major highways in the world in 1887, and the first road to Ba'al was built in 1936.
As the national road system began to be developed, the need of keeping the roads free of danger became increasingly important. Rilakshmi had built many roads on the island of Barents Sea, and the Rilakshmi Hobbits of Varda held the title of "road-builders", for they built roads and bridges across the sea, including Rilakshmi's famous road-bridge to the Grey Havens. The road in question was a fifty-foot-long, half-crossed bridge over the river Hithlum, and was twice as long as nearby bridges of the same diameter. The road near the Grey Havens, constructed by the Rilakshmi Hobbits, was destroyed in the War of Wrath. The bridge was rebuilt in the year 508 of the Second Age. Later, travel by horse and camel became so common in the Middle East, and by the early ninth century, the average annual rate of traveling by camel was a mile per day, and the average year's travel was around 50,000 miles (80,000 km). One of the first reviews of travel by camel was written by the legendary traveler Ibn Battuta, who traveled mainly in the Arabian Peninsula, and documented the journeys of camel caravan in his book Travels to the Holy Land in the Year 932. The book was published in 1073, and Ibn Battuta considered his travels to be the first "discussion of travel by camel" (ibid, 1084).
The following year, the Chinese traveler Zheng He wrote a detailed description of his journey to the Holy Land with the help of a camel, which he named "Zhengzheng" (meaning "camel-camel").
