Hmm I wonder how much the decision to arrive was influenced by the decline as orders of priority. Say in a simplified gamey heuristic: 1. If there are boats or coastal settlements around the island and decent canidates attempt trade to fulfill needs - it is lower risk and where the greatest speed and cargo volume may be obtained. 1a. If trading won't be sufficient and they appear weak enough to gamble raid - it might get you killed but greater riches. If you would starve anyway what do you have to lose? (That infamous practice while it may have saved them from harsh winters got their civilization effectivly after the profession of raiders - it would be sort of like calling all of England and their descendants pirates.) 2. If the land is decent and under or unsettled land to fulfill needs - it is slower than boats and has lower cargo capacity. Also less likely to find undefended farmland or similar assets. Essentially if the population didn't decline they never would have bothered heading inland more as either boats and coast fulfilled their needs better or if in bad relations scared off as the type of place that would rob or kill them on sight.
