Drasil is the largest city in the continent of Guiltina, so named for being the site where Aldoron, the Wood Dragon God, has sealed his power, with multiple venues as well as a large population of citizens. The city itself consists of five towns built on different points across Aldoron's body: one on each hand and shoulder, and one on the center of his back. These towns are called Left Hand Town (左手の町 Hidarite no Machi), Right Hand Town (右手の町 Migite no Machi), Left Shoulder Town (左肩の町 Hidarikata no Machi), Right Shoulder Town (右肩の町 Migikata no Machi) and Back Side Town (背中の町 Senaka no Machi). Aldoron also rises during a certain time every day, which causes mostly harmless tremors in the towns.
Drasil is located at the center of Guiltina, built upon Aldoron's body.
Drasil is a combination of the words "dragon" and "seal", which is a play on words in reference to Aldoron and his created God Seeds containing his power through the use of five orbs located in every city of his body.
