Situated in the easternmost point of Calvard, Longlai serves as a gateway to East Zemuria. Together with its famous hotsprings and cultivation of tea herbs, it is a popular destination for many foreign tourists. The desertification of East Zemuria, however, resulted in a decrease of tourism in Longlai.
Longlai's cityscape is made up of Eastern-style buildings only, giving it a unique atmosphere among places in Calvard. Unlike Crossbell City's East Street, it has a subtle and profound beauty that conveys its history through tranquility, evoking the aesthetic of wabi-sabi. It is famous among practicioners of the three Eastern martial arts schools: Taito, Kunlun and Gekka.
- Hekizanrou (
碧山楼), a high-end, traditional inn.
- Longlai was first introduced in Trails of Cold Steel III as a region known for its green tea.
- Like Ymir, Longlai is known as a Hot Springs Paradise (温泉郷・龍來).
- The Kunlun Range (
崑崙) has been visited by practioners of martial arts since antiquity.
