This is my final submission for the artstation challenge Lightbox Expo: Box of Mystery.
In this world Atlantis is an underwater capital city of the merman folk which is many centurys old. Much older than the history of men go back in time. For this challenge I will focus on a powerful artifact (obviously a box) which once was forged by gods and provide the city with energy and life. For merman its an honor to guard it.
Atlantis was build on the vulcanic rocks of rhyolite. Also the architecture is a mix between corals and merman-made structures. To keep the water circulate, the city's structures are open-ish to allow to enter it from every angle.
