It is known that Triumvirate Holdings was involved in previous wars. During the Second Titan War, Triumvirate Holdings supplied @Luke Castellan and the @Titan Army with the Princess Andromeda. Then, in the Second Demigod Civil War/Second Giant War, the Triumvirate supplied @Octavian with monsters such as cynocephali, as well as providing Camp Jupiter with weapons for the Siege of Camp Half-Blood.
Timeline of Battles
Nero's Skirmish at Camp Half-Blood
@Nero along with two bodyguards used the @Labyrinth to enter the @Ant Hill. He intimidated @Margaret "Meg" McCaffrey (Apollo's master) into ordering @Apollo to open the gates that led to the @Grove of Dodona. Nero had also taken five campers and a geyser god prisoner tied in cocoons to wooden posts outside the gates. Nero set fire to the grove and fled. Apollo was unable to put the flames out. A legion of Dryads, however, came and summoned mud from the earth and were able to extinguish the flames before too much damage could be done to the grove, which costed them their lives. Apollo was able to free his son, @Austin Lake, who started freeing the prisoners from the cocoons they were in. It was at this point Meg left to go to Nero. While this was going on, Nero's colossus had arrived and was attacking the camp. Apollo convinced the "Mama" Myrmeke to take him and the demigods to the camp grounds (which she and two other Myrmekes did). It was there that Apollo found the colossus destroying the rest of the camp.
