The Silent Column is a romance visual novel - boy pursues girl - which takes place after the events of 'the fall,' a supernatural event which resulted in the deaths of most people in the world.

In the aftermath of that terrible time, Tashen and his small, family-like unit live quiet lives as they meet new people - such as the mysterious Amy, the intimate Thidria, and the energetic Serra.

As time goes on, Tashen finds himself surrounded by strange and abstract mysteries... some of which are older than the sun.
