Through the Silent Sea of Trees lies a world of ice and snow that has been standing here since time immemorial. Legend says the storms raging here can freeze even space itself. Ancient whispers haunt the ear, and scatter in the biting wind, leaving everything plunged back into utter stillness. The intruders try to grasp and understand that sound, but their thoughts have been frozen solid, turning into an ice sculpture that adorns the brutal cold of this wasteland. Here is the Frost Wasteland.

The centaur clan has dwelt here for untold generations. In this frigid realm, their ancestors developed a bonded device called "JI TIE". Every clansman is born with one JI TIE bound to them. A tiny fraction of awakened ones can evolve their JI TIE into a second form, becoming the ‌Black Lead Cavalry‌. In the name of the glory of their tribe, they arm themselves with shield and spear, fight back all invading enemies. One against a thousand!
