Lyric's Lair

Lyric's Lair is the ninth and final area of Sonic Boom: Rise of Lyric. It is the central headquarters of Lyric the Last Ancient. Easily the darkest setting in the game, it is a nightmarish and highly technological fortress filled with deathtraps and robot armies, located in a lifeless waste. Being build for Lyric himself, this place is a terrifying example of Lyric's twisted plans for the world: a death place devoted of organic life and ruled by nothing but soulless machinery.

When Lyric stole the Chaos Crystals from Team Sonic, the team pursued Lyric to his lair, intending to face him in a final showdown for the fate of the world to stop him from activating his Sentinel army and wiping the planet clean of all organic life.

Story
After making a crash landing with the plane, Team Sonic began fighting through the metallic fortress, determined to prevent world destruction. With the help of Q-N-C, they were given a way to keep on going until they found the villain lurking at the end.

Team Sonic arrived at a power generator, with all the Chaos Crystals attached to it. Lyric had just activated his army of Sentinels, sworn to finish what he had started a thousand years ago. The snake sees Sonic and his gang, and though he was annoyed at their presence, he tells Sonic that he finally knows his weakness: his friends. Sonic says he is wrong; as they aren't his weakness, they are his strength. Thus heroes and villain began their final battle.

After the fight seemingly ended, Lyric notices the Enerbeams and uses the device on his armor, to manipulate the Enerbeams to wrap around Team Sonic. When he was about to finish them off, Eggman appears, using his mech to hit him from behind, causing the Enerbeams to deactivate. Team Sonic, working together, were finally able to tie Lyric up, leaving him helpless and defeated. They saw a portal suddenly appear, and out came Shadow, who was ready to fight them once again but upon seeing that they already stopped Lyric; he turned to leave while giving his approval. Sonic and Knuckles went to Lyric, taking off the device on his suit, and throwing it far away, shutting down the Sentinels. After everything they did, it was time to go back to town and celebrate.

After the credits, it's revealed that the device Lyric used to control the robots had been found by Eggman, who used it to replace his wrist device's button with Lyric's, laughing maniacally as he pushed it, reactivating Metal Sonic in the process.
