Talesweaver is based on the popular fantasy novel Children of the Rune (author Min-hee Jeon). Characters featured in the novel appear in the game, participating in stories beyond the original novel.
The game is set in a fictional kingdom called Anomarad. There are four major cities that the player can travel to: Narvik, Laydia, Clad and Kaul. Other major cities have been added in Episode 2, such as Keltica, Eltivo and Cardiff.
The game is a 2-D MMORPG, with a viewing angle of about 60 degrees. The characters in Talesweaver come at different levels and with a variety of different skills through which they can be developed. The skills are "leveled up" by using experience points, rather than skill points. All skills use MP, and buff skills along with the more powerful skills use a number called Environmental Points. Environmental points are shared along every character nearby each other, and have a default of 999. Environmental points regenerate faster than MP, with almost a 10 to 1 ratio.
