Objective: throw charges at the orange orb in the air, pushing it towards the central tower. The event will start and the center tower will raise along with 1 of the 3 auxiliary towers. The auxiliary tower will have a glowing orange orb in it. The active aux tower will be under heavy fire from the enemy. The area around the tower must be kept clear and free of combat, or else it will not produce enough charges. A clear tower will produce 6 charges, while a tower under attack will only produce 2. It will take ~10-12 charges each time a new aux tower is activated, and you need to push the orb to the center 6 or 7 times. There is a progress tracker with the timer, as well as visual cues in the center tower. What happens when it's at 100%, I still don't know yet. I'm posting this to help as many people as I can so that success becomes more dependable.
