Snuckles was so relieved that the Tech Skylanders were here! "Okay, I've got good news and bad news!" He said. "The bad news is that the enemy has the advantage! The good news is, now that you're here, you can help us get to the Command Team!" Agreeing to help, the Tech Skylanders made their way through the combat zone and managed to get to the Command Team. There, Rizzo told them what was happening. "We need to get past their barriers, but we aren't having any luck." He said. "The good news is we've captured a troll stockpile, and there's a Mega-Bomb inside it! Ha! Good for our side. The bad news is it's too heavy for any of us to move! Me included! Too many years planting flowers, I suppose. Looks like a job for you!" Luckily, the Tech Skylanders were able to breach the walls, but the trolls were waiting for them! "SURPRISE!" The four Skylanders dodged a shell from a tank! But not just any tank! "Behold, our secret weapon: The Troll Super Tank!" The General taunted. "This baby is powered by the Eternal Tech Source itself! Good luck destroying this!" Then, the battle began! Trig shot the tank, only to have the coins bounce off! He then threw a pot of gold to get their attention, then unloaded his machine gun on them! Drill Sergeant snuck up from behind and drilled into it! He used his rockets to damage the main body, then shot the drivers with his Auto-Cannon. Drobot provided air cover, kicking up his afterburners to deal with pursuers. He launched bladegears to stun the tank, then did a bombing run with his wing and eye lasers. Boomer then threw a stick of dynamite, but the General, who was driving the tank, caught the stick and defused it! "Any last words, traitor?" He asked, pointing the gun at the troll. "Just one: BOOM!" Boomer then smashed the ground as hard as he could, then kicked a Troll Bomb into the tank's engine, blowing it up! "LORD KAOS!" The General wailed as he was blown away by the explosion. "I'VE FAILED YOOOOOOOOOOOOUUUUUUUUUUU!" As the smoke cleared, all that was left of the tank was its power source: The Eternal Tech Source! Now, the Core of Light was almost nearing completion!
"At last, the Eternal Tech Source!" Eon said. "Embodiment of all science and lesion, balances match in the Core of Light!" The Tech Source summoned two floating orbs and descended into the Core. Drobot sensed the goo within the vines underground begin to glow, and the gears started to turn, along with the Core's base. Now, only three sources remained.
"You know, Glumshanks," Kaos said to his troll butler. "Despite your colossal failures, exemplified by you mutton-headedly losing the Eternal Tech Source, I am feeling particularly optimistic and do you know why?" "No?" "Because, the Darkness is becoming more powerful! It's spreading all over Skylands! Soon, no one will be able to stop it! HAHAHAHAHAHA! You know what they say, red skies in the morning, Skylanders take warning!" "No one actually says that."
"Superb job Skylanders!" General Robot congratulated. "You've done Skylands proud!" However, the Undead Skylanders started to sense something. Hex concentrated. "The door." She said. "At the beach. It's opening." General Robot instantly knew what this meant. "I-I might be a great g-g-g-general," He stammered. "B-b-but when it comes to the supernatural, I am O-U-DOUBLE T- OUT! T-t-this is my last HU-rah! G-g-good luck with the war, soldiers!" He then made like a tin can and fled. Cynder looked at her allies. "The Undead Skylanders and I will go check it out." She said. Chop Chop readied himself. "Be on your guard." He warned. "We do not know what lurks behind those doors." The four showed no fear as they faced the skull-like door. "I hope there's ghosts!" Ghost Roaster said. "I love eating ghosts! Especially evil ones!" Cynder was a dark dragon who had been taken in by evil, and like Spyro, she was from another world. Chop Chop was an Arkeyan looking for a master, and he saw one in Eon. Ghost Roaster was a spirit who was chained as punishment for eating spirits. He was also a great chef. Hex was once an elven sorceress who was given evil powers by Malefor, who Cynder appeared to know. Then, the doors slowly opened with a creek. The four readied themselves. Then, something came out of the shadows yelling "BOO!" Chop Chop attacked, but his sword stab missed as it struck the sand next to…. A talking skull. "HEY! What gives?!" The skull asked. "I was just saying hello!" "Be glad we are not frightened easily." The Arkeyan said as he and the others let their guard down. "What are you doing here?" "Well, the name's T-Bone, and I'm a skeleton. At least, not much of one right now. Seem to be missing a bone or two. Or 204, more like. Anyway, can't seem to find my body right now. Embarrassing, I know." After T-Bone's body was restored, the Undead Skylanders told him the story so far. "So now we need the Eternal Undead Source. Know where it is?" Cynder asked. "Well, if I heard from the living correctly, an Eternal Undead Source needs a holder. Maybe the Skull Mask of the Undead King Mortalannis might do it. Last, I know, I think it was in the Crawling Catacombs. I can take ya!" Chop Chop groaned. Clearly, this literal bone-head might be too stupid to know what "an" Eternal Undead Source is so important for. He thought. As he and the other took the stairs down to the catacombs, the door closed behind them. "Funny." The Arkeyan said. "We can never be trapped down in the Underworld forever."
