Primal Swamp
A mysterious place on Cybertron, home to legends and myths, and sometimes the Dinobots, Predacons, or both.
In some continuities, it holds the Requiem Blaster. In others, it's a place of wonder, mystery, and very territorial creatures.
Prime Wars Trilogy
After Optimus Prime died to Megatronus, who spilled his master plan to resurrect his beloved Solus Prime at the cost of Cybertron's population, Megatron hit on the idea to go beat him to the Requiem Blaster, the only artifact of the three required for the Fallen Prime's plan that was still up for grabs. After consulting some religious scrolls, Megatron, Perceptor, a one-armed Victorion, and Windblade went on their merry way to the Primal Swamps. After walking through some metal poles that looks suspiciously like robot bamboo and giant metallic grass, they were ambushed by the Dinobots. After tossing them around a bit, the attackers combined into Volcanicus.
He promptly wiped the floor with them, demanding the Enigma of Combination, thinking he would need it for the looming apocalypse. Fortunately, Predaking soon arrived for the same reason, and the two combiners scrapped with each other over territory and Enigma rights. This provided an excellent opportunity for the Old, Smart, Big, and Righteous crew to get out of Dodge. The two combiners noticed this, however, and Volcanicus came running, Predaking hot on his heels. Megatron came across a dome decorated with the symbols of the Thirteen Primes. Meanwhile, the rest of the Smart, Big, and Righteous crew were cornered and outgunned. Fortunately, the brawl between the Primal Rivals resumed, with Volcanicus getting stuck in an Energon spring and having to decombine to escape.
Inside the dome, Megatron and a strange ape robot were finishing a fight which ended with the former coming out of the dome with the Requiem Blaster and pointing the big gun at Predaking. Cowed, the combiner retreated, only after Megatron promised to let him know when they found the Enigma of Combination. Soon after, Grimlock decided to join the now Old, Smart, Big, Righteous, and Prehistoric crew to find the Athenaeum Sanctorum. A short while after they set off, Overlord and a corrupted Rodimus Unicronus, fresh from interrogating/murdering Menasor, Devastator, and Computron (He died twice now), decided to do the same to the Dinobots for info on the quest group's whereabouts. They got it from Snarl, and Overlord released his lot. Rodimus Unicronus just decided to snap Sludge's neck to prove a point. Much later, after Megtronus's defeat, Optimus Prime's resurrection, Optimal Optimus's upgrade, Hot Rod's purification, and Megatron plus Predaking's collective demise, the Dinobots were seen in the Primal Swamp mourning Sludge's death.
