it's a series of maps, to be exact.
First Map: Lord 1 arrives at location. A standard arrive map, however...
how long you take here affects the map after. Let's say it takes 'X' Turns.
Second Map: Defend with Lord 2.
A super tough defend Map where you are getting attacked from all sides.
You gotta defend for 'X' Turns. The amount it took you to finish the other map.
After successfully defending, Lord 1 and their Party appear and now the enemy army is sorrounded. Eleminate them. Enemy gets stat debuffs due to being demoralised.
