Webzen is expanding content such as an original soundtrack and web novels using the intellectual property (IP) of 'Terbis', a new subculture title it is developing in-house.

Webzen said on Oct. 29 it released 2 'Terbis' OST singles, including 'The Prayer of Terbis' and 'Dream in Blue', on major music platforms such as YouTube Music and Melon on Oct. 28 in single-album format.

The two songs were included in a previously released 'Terbis' animation promotional video (PV). The new release allows listeners to hear the full tracks.

'The Prayer of Terbis' consists of a vocal version and an instrumental version. Voice actor Bona Kim (김보나) sang the Korean version, while singer Shiori Niwa (니와 시오리) sang the Japanese version.

'Dream in Blue' features lyrics and vocals by Asaka (아사카), who works in Japan as a singer and voice actor.

Webzen has been rolling out content using the 'Terbis' universe and characters even before the game is released.

In July, it took part for a fifth consecutive time in the Japanese subculture event Comic Market, introducing the game's main characters and content. In September, it began serialising the web novel 'Terbis: The Embodiment of Omnipotence' on Naver Series based on the game's universe.

Webzen plans to continue releasing 'Terbis'-related content and marketing information through its official social media services (SNS).
