Dauntless Defenders

(Rule)
Description: At the start of the first battle round, select two objective markers on the battlefield to be your foundations. When you draw a line from any part of one of your foundations to the other, if any part of a model's base (or any part of a models hull, for a model without a base) crosses that line, that model's unit is said to be on your defensive line. While an **^^Imperial Knights^^** unit from your army is on your defensive line, that unit has the Against the Horde ability. Each time one of your foundations is removed from the battlefield (e.g. by a Primary Mission rule), just after is is removed, select a new objective marker on the battlefield to be one of your foundations.
