Back in Civilization 1, there was a tutorial tip early in the game: defend your cities with "preferably two" good defensive units.
If only Hotu Matu'a had followed that timeless advice...
No Barbarian incursions into Rapanui territory had occurred in centuries. I had attributed that to the thriving Inca Empire to the south, which had expanded into the Amazon Basin. (Remember, on this variant of the Earth 18 Civs map, there are two land routes out of the Andes, which I added to reflect the locations of IRL passes.) So it came as a great surprise to the citizens of Mataveri and their lone regiment of Archers when Barbarians showed up on horseback (where can you even get horses in South America?!) and slaughtered them. The Civilized Peoples were ultimately victorious, however, when the Barbarians marched on Hanga Piko and were mowed down by the Archers there, who were out for revenge.
Oops.
Resources were still as scarce as ever for raising an army... But new land waited to be colonized without fear of Barbarian incursions. Scientists in Hanga Roa discovered how to make magnifying devices out of glass, and soon reported discovering new land to the west, near the new settlement of Vinapu, which was primarily a fishing village on one of the more easily-accessible Pacific islands. However, it was just out of their reach for the time being, across a stretch of open sea too dangerous for their simple Galleys to cross...
Around the same time, first contact was made between the Hindu World and followers of other organized, widespread faiths. Though early diplomatic contact thankfully stopped short of hostilities, the foreigners were certainly not pleased to hear the other side call them heretics, and showed no interest in opening trade relations, no matter how politely and enthusiastically the adventures of Lord Krishna were related to them. Curiously, these two new peoples, who arrived in Rapanui lands together, were followers of different religions: the French were Christian, but the Germans were Buddhist. France arrogantly demanded tribute from the Rapanui, and the frightened rulers decided, after some deliberation, to pay, since they had no idea what kind of army the French might have, or how swiftly it might arrive. The foreigners were not to be trusted.
(I'm not going to post any first contact pictures; it takes up too much space, and you know what the leaders look like. A few turns later, I met Asoka, Qin Shi Huang, and Tokugawa (all Buddhist) in rapid succession.)
The situation was complicated by the apparent existence of three more Buddhist kingdoms to the West of the Hindu Countries which held each other in a network of feudal obligation. To anger one was to anger them all. The Rapanui began to feel truly threatened for the first time. The solution, decided the nobles, was to take more land for Polynesia before the foreigners could get to it, to try to stop the spread of their influence and to seek out the resource-rich lands needed to create a strong army to resist them. (And, they said secretly amongst themselves, to secure somewhere to escape to, should their worst fears come to life and one of these far-off countries massacre their people like the Barbarians had at Mataveri.)
