The Terran Dominion, the Protoss Golden Armada, Glorfindel, and Gloin traveled to Mirkwood. The elf messenger led Glorfindel, Gloin, Selendis, Matt Horner, and Johnny Raynor to king Thranduil. "Thranduil, I would like to introduce you to Executor Selendis of the Protoss fleet, Admiral Matt Horner of the Terran Dominion, and Johnny Raynor son of Jim Raynor. They're allies of Jim Raynor and have come to aid you," Glorfindel introduced his allies.
"Jim Raynor? Where is he?" Thranduil asked.
"Jim is far south in Minas Tirith. He, his men, and the other Protoss will handle the main Mordor army," Horner replied.
"We have come for an alliance between your people and the Dwarves. We share a common enemy that has to be wiped out," said Gloin.
"I will see about the alliance, but right now I have a kingdom to defend," said Thranduil.
The leaders gathered for a mission briefing and Selendis asked, "What do you know about fighting in an environment like this forest?"
"There's no way for our air forces to support us. We cannot use siege units as they won't fit into the forest," Horner replied.
"So just go with infantry?" Johnny asked.
"I hope not," said the Dominion admiral. "Any combat walkers like the goliaths, dragoons, and immortals can work. Our fast vehicles can't maneuver through the forest."
"Excuse me for the interruption," it was an elf captain. "Sauron's forces from Dol Guldur along with goblin forces are in the forest."
"Let's go," said Thranduil.
The Golden Armada sent a force of zealots, dragoons, sentries, and immortals. The Dominion force made up of marines, marauders, firebats, and goliaths. Thranduil's had his archers that specialized in stealth took their positions then ambushed the orcs, goblins, and trolls. Enemy forces came in greater numbers causing the Protoss and Terran forces to engage them. The zealots sliced the orcs and goblin infantry into pieces. The firebats caught multiples of orcs and goblins on fire causing them to run around then collapsed motionlessly. The marines, goliaths, dragoons, and immortals opened fire at the hostiles. The marauders picked off the trolls while the sentries fired their beams to attack any hostiles.
"I'm reading hybrids coming towards us," said Horner.
The Protoss and Zerg hybrids were powerful monsters that served Amon and could not be defeated by any small measure. The hybrid dominators and behemoths had the abilities to detect Mirkwood archers. A hybrid dominator and behemoth acted like the leaders of the hybrids. The Mirkwood archers released arrows on the hybrids however they bounced off the monsters. A number of elves were clawed and shot by the hybrids.
"What are these monsters?" a Mirkwood archer asked.
"They look as if they're from another world," said another elf archer.
"How come Sauron have such powerful creatures?" a Mirkwood archer spoke as if he did not get it.
The combined forces of Terrans and Protoss helped them out. The immortals drew the hybrids' attention while the zealots charged to slash the zerg-based hybrids. The marines, marauders, dragoons, goliaths and immortals concentrated their fire on those monsters. A hybrid dominator unleashed psionic storm on the group of ranged attackers causing them to spread out. When an immortal's shields were drained, it activated a barrier to absorb additional damages. A few zealots, marines, and marauders were killed by hybrids while few of the machines were destroyed. Eventually, the forces of Amon and Sauron were repelled. The Dominion medics treated the wounded while the SCVs repaired the machines.
Laketown was rebuilt 60 years had passed since Smaug's death but Sauron's army launched an assault on the town. King Fili led the dwarven army to aid the people of Laketown to repelling Sauron's forces and sent a messenger to Mirkwood requesting aid.
A dwarf approached the leaders requesting aid on the Lonely Mountain. "You can tell your king that the allies of Jim Raynor will come to aid you in my stead," Thranduil replied to the messenger.
"I'm going to help my people out," said Gloin.
"I'm coming with you," said Glorfindel.
"We'll be using ships to aid them," said Selendis.
The Golden Armada used a fleet of tempests that were long-range siege auxiliary ships and carriers that were capital ships that used robotic interceptors to swarm foes whereas the Terran Dominion used a number of battlecruisers that had abilities of tactical jumps and yamato cannons. Gloin, Glorfindel, the Golden Armada, and Terran Dominion left Mirkwood for the Lonely Mountain.
King Fili received bad news that the elves would not help them but the allies of Jim Raynor were coming. The dwarves and men of Dale defended the Lonely Mountain from the Mordor army. Dwalin, Nori, Bifur, Bofur, Kili, the elf Tauriel, and Bran the current king of Dale participated in the defense. The first wave consisted of orcs that were infantry and crewmen for the battering rams and long-range catapults. The second wave made up of corsair looters and Easterlings. The third wave consisted of mountain trolls, drummer trolls, and armored trolls that wielded spiked maces.
"Now meet your fate, primitives," the last wave of foes came in the form of creatures that the dwarves had not faced before. Those powerful creatures overwhelmed the dwarven and human armies.
The skies were filled with flying machines the dwarves and men of Dale had never seen before. The powerful monsters turned to attack those flying machines attempting to take them down. Some of the machines fired at the monsters with their weapons and some launched minions to swarm those monsters. Eventually, the powerful fleet eliminated the first wave.
A flying machine landed and unloaded Gloin, an elf in silver armor, and three strangers. Gloin introduced Glorfindel along with Selendis, Matt Horner, and Johnny Raynor as allies of Jim Raynor to King Fili. He, his brother, Tauriel, the other dwarves, and Bran learned that Jim was in Gondor. They also learned that the monsters were hybrids bred by the dark god called Amon who was in league with Sauron. The elves, dwarves, the Golden Armada, and the Terran Dominion planned to assault Dol Guldur.
