In 2006, a group of friends, all seasoned adventurers, stumbled upon an ancient map while exploring a dusty, old bookstore in Jakarta, Indonesia. The map depicted a mysterious island called Tanaja, rumored to hold the secrets of a long-lost civilization. The group, consisting of five friends - Arman, Rina, Tono, Lesti, and Bowo - couldn't resist the temptation to embark on a quest to uncover the mysteries of Tanaja.
