Daewangam — Munmu's Dragon Secret
You are a guardian of the Silla royal lineage, in Gyeongju, 7th century AD.
Your mission is to thwart a plot aimed at weakening the royal family, echoing the protective spirit
Delve into the millennia-old legends of Silla, Korea's ancient kingdom, where kings defied the heavens and dragons protected dynasties.
The story that haunts this land
Your journey in Gyeongju begins at the Cheomseongdae Observatory, National Treasure No. 31 of South Korea. Built in 647 during the reign of Queen Seondeok of Silla, this 9.17 m high stone astronomical observatory is one of the oldest preserved in East Asia. Its 365 stones represent the days of the year, and its 12-stone base symbolizes the months. Here, the stars whispered the secrets of royal destiny, and it is within its walls that the first clues of your quest appear, guiding you to the roots of the Silla lineage.
Continue your investigation in the Gyerim Forest (계림), a legendary 7-hectare site, planted with ancient trees and a place of Shinto rituals. It is here, around 69 AD, that legend places the birth of King Kim Alji, mythical founder of the Silla royal lineage. Mentioned in the Samguk Sagi (1145) as the birthplace of the founding king, this area is classified as National Treasure No. 33 and houses a commemorative stele from 1964. Do the ancient trees of Gyerim conceal traces of the first plots against the monarchy, or are they the silent guardians of a sacred heritage?
Your inquiry then leads you to the Donggung Palace and Wolji Pond (formerly Anapji Pond). Built in 674 under King Munmu of Silla, this secondary palace, with its 21,205 m² artificial lake, served the princes. Restored in 1975 after archaeological excavations (1971-1975), the site includes 3 ponds and 2 main pavilions, now illuminated at night since 1978. The Wolji and Seunghwangjeong pavilions are classified as National Treasure No. 18. It is within this lavish setting, where royalty relaxed, that you must decipher messages hidden in the water's reflections, revealing rival ambitions within the court.
Your journey through Gyeongju's heritage takes you to the Hwangsunsa Temple Site (황룡사지). Founded in 553 by King Jinheung of Silla, this temple once housed an 80 m high 9-story pagoda, destroyed in 1238 by the Mongols, but a model of which was reconstructed between 2017 and 2021. This 200,000 m² site, excavated since 1975, has revealed 40,000 tiles. Legend has it that King Munmu wished for its reconstruction before his death in 681. These ruins, witnesses to grandeur and destruction, hold the keys to forgotten prophecies and secret alliances that marked the history of Silla's ancient capital.
Finally, your quest concludes at the Woljeonggyo Bridge and the Poseokjeong Site. The Woljeonggyo Bridge, rebuilt in 1678 under the Joseon Dynasty, spanning 33 m over the Anapji River, is a National Treasure No. 33 and listed as a UNESCO World Heritage site in 2018. It leads to the Poseokjeong Pavilion, an L-shaped granite shelter, dating from the 8th century under King Gyeongdeok, with a 1.7 km channel for floating stone games. This imperial banquet site, excavated in 1917, is a National Treasure No. 18. It is here, between Gyeongju's flowing waters and ancient stones, that you will piece together the last parts of the puzzle, thus protecting Munmu's dragon legacy and ensuring the continuity of the Silla royal lineage.
