The PoD would occur in the Western Steppe Region, near modern Ukraine and Russia, during the time of the Punic Wars. It would involve a steppe army of horse-archers coming into contact with Roman armies during times of war with Carthage.
This timeline would involve a steppe army following the path of the IOT Hunnic invasion. The invaders would disrupt the Germanic tribes, starting a domino effect very similar to that caused by the Huns. This would progress until Celtic and Gallic tribes began to make their way into the Italian and Iberian peninsulas. Depending on when in the course of the Punic Wars this started, I see it going one of a number of ways. If the tribes were to land in Italy during the Second Punic War, while Hannibal remained there, I highly doubt that Rome would have survived. It would most likely be conquered by the tribesmen in the North, and by Hannibal in the South. Even if the invasion were to come at a time in which Rome had the upper hand in the conflict, there is little chance that they could fend off the tribes in the north and the Carthaginians in the south. After Rome fell to the Barbarians, I predict a kingdom similar to Odoacer's, or any of the other post-Imperial kingdoms that spring up IOT to govern the peninsula temporarily. After Rome fell, the barbarians would be unlikely to extend past Sicily without advanced naval capabilities.
Now to the Iberian peninsula. I predict a steamrolling of Carthaginian Spain, and Barbarian army looking across the Straight of Gibraltar within two or three campaign seasons. Now is the moment in which the exact moment of the PoD is important. If the invasion occurs in the first or early Punic war, Carthage would, most likely, be able to use their navy to keep the barbarians out of Africa. If it is during the later second or third Punic war, I predict the fall of Carthage as well. I predict the Antigonid Macedonians and the Seleucids defending the Eastern Mediterranean, but perhaps losing some territory in Northern Anatolia.
So far, I have operated under the assumption that either a) the Steppe invaders settle somewhere in Northern or Central Europe, or b) said invaders are slowly making their way South, subjugating or massacring all who do not flee before them. If we can assume the second to be true, around the time of the capture of Carthaginian Spain, the Steppe tribe will begin to reach the extent of the former Roman Republic. Having nowhere to go, the Gallic, Celtic, and Germanic tribes in Italy and Iberia would be completely subjugated. Once again, if the Carthaginian navy was able to end the European barbarian advance, it would be able to end that of the Steppe tribes as well. I will end the speculation at a united Western Mediterranean Europe under steppe nomadic leadership, similar to the Xiongnu in Manchuria, or the Parthians in Persia.
