The Green Festival, L'Manberg Festival, or the Winter Festival, was a festival hosted by L'Manberg. The festival was conceived shortly by the Butcher Army with the intent to kill Dream after Quackity suggested that the sole reason Technoblade escaped his execution was aid from Dream. He and the Butcher Army then came to the realization that Dream was behind all the chaos on the server and decided to put an end to Dream's grasp over L'Manberg and the Greater SMP by killing him in a festival reminiscent of the Manberg Festival.
On January 4, 2021, Technoblade terrorised L'Manberg by spawning a wither. The wither did some damage to the nation and the festival's decorations. In addition, knowledge of the festival was shared to Technoblade, TommyInnit, Vikkstar, and Punz. The mess was shortly fixed by Ranboo.
Before the festival started, Tubbo talked to Ranboo, stating that he was a perfect example of Law 5 of L’Manberg: “Be Loyal”. As the festival started, the L'Manberg Cabinet gathered at the podium, where Tubbo gathered everyone and gave a brief speech about his desire for everyone to band together as a community and have some fun. The group started playing several rounds of ring toss and other games installed. While the others played happily, Quackity pulled Tubbo to the side, beginning to worry about Dream having not shown up yet. Tubbo reassured him and himself that Dream said he'd be there after it started, and without armour, their plan would still be underway.
Despite killing more time, Dream still had yet to show up, and Tubbo and Quackity once again met in private, this time in Ghostbur's underground home. Tubbo then received word that Dream would be running a little late, leading Quackity to stall more time. After Tubbo suggested that they play manhunt. He put the target on Fundy, and Quackity and Tubbo snuck away to discuss their next move. Puffy quickly caught and killed Fundy, and Ranboo used the opportunity to sneak away to meet with Tommy and Technoblade and inform them of everything that was going to happen at the festival. After losing interest, everyone then regrouped in L'Manberg.
The Butcher Army then met together to discuss the final details of the plan. They agreed that Fundy, Quackity, and Ranboo would be on the podium giving a speech, while everyone else, including Dream, would be standing in the center without armor. Tubbo would then pounce Dream, taking him by surprise and killing him. They then discussed a signal for when Dream arrived, but were interrupted in their efforts with Dream logging on.
Shortly before Dream's appearance, the Army was interrupted by obsidian walls beginning to be built around L'Manberg by Dream. The cabinet began to question Dream as to what he was doing, and Dream immediately began stating that Tommy had messed up for the last time, much to their confusion. Dream believed that they were lying and led them to the Community House. There, they saw for the first time that it had been completely destroyed. The festival abruptly ended, and the crowd began traveling to the house to observe the conflict.
Tubbo explained that L'Manberg didn't know that it was going to happen and had nothing to do with it. Dream retorted that it had everything to do with Tubbo because he had one Tommy's discs, which still connected him to Tommy and gave Tubbo responsibility to enforce the exile. Dream then demanded that Tubbo hand over the disc to give Dream full power to enforce the exile.
However, the meeting was interrupted by a previously invisible Tommy. Tommy denied the accusations that he had done the damage and asked Tubbo to not hand over the disc. Technoblade then appeared as well to say that it wasn't Tommy's fault, which Dream rebuffed by claiming that Tommy was the biggest liar of the server. Tubbo opened the ender chest to take the disc only for Tommy to push him away and express that Tubbo has been a bad friend despite Tubbo's belief that Tommy was the one at fault. Tommy asked Tubbo to trust him, but Tubbo replied that he did once, and that he wouldn't make that mistake twice. Tubbo then took Mellohi out of his ender chest, and Tommy yelled at Tubbo, expressing that Tubbo had betrayed him.
After Tommy demanded that Tubbo drop the disc, Dream hopped down into the center asking for it. Tubbo dropped the disc, and he and Tommy began to apologise to one another. Tommy realised that he wasn't the person he wanted to be, and he was becoming worse than everyone he wanted to be better than. To prevent himself from becoming any worse, he told Techno that he wasn't going to help him anymore, effectively betraying him. Techno gave him one last chance to rejoin his side, but Tommy declined.
Dream then began to berate Tubbo for giving him the disc, pointing out how horrible of a president he was and how easily he let himself be pushed around. He continued by revealing that he had simply been using Tubbo to get the disc this entire time. Then, Dream exposed Ranboo as a traitor to L'Manberg by handing Tubbo a copy of Ranboo's memory book titled "do not read". Dream then stated that L'Manberg would be destroyed at 3 p.m. EST January 6th, just about 21 hours away. Dream then left the ruins of the Community House.
After Dream and Techno left, Tommy stood in front of everyone and tried to band everyone together to fight against Dream. He apologised to everyone for everything he had done and told everyone that they needed to put things aside so that they could save L'Manberg together. Most members were hesitant to join Tommy after what Dream accused him of doing. Sam made him swear on something important that he didn’t do it which Tommy then swore on the Church Prime. Niki still didn’t want to fight for a country that had betrayed her, and Quackity was livid that he had been working with a traitor, Ranboo. Ranboo claimed that he was never one anyone’s side, making it harder for the group to come together to fight for L’Manberg. Fundy brought up the point that they shouldn’t fight for other people but for the country, getting some people to reluctantly join. Tubbo expressed gratitude for those that decided to fight against Dream. Eret then offered his fortress to be their base of operations before declaring tomorrow to be "Doomsday".
