To relay orders during battle, the mighty Ùnfhynihed clan uses the projections of masks through light. When this projection reaches the standard-bearer of a unit, it follows it. 

The objective of each level is to take control of every light tower on the map. To take control of a light tower, you must bring a standard-bearer next to it. Progress to the last levels to unleash powerful curses and bonuses.

[Controls]

Click on an activated light tower and use the buttons on the bottom right to choose which order to project. Then, drag the projection around to the desired unit's standard-bearer.

Activate a new light tower:  Place a standard-bearer next to it.
Some units carry a mask. Bring those units to a light tower to allow its use by that light tower.

[Purpose]

Activate every light tower on the map.
