As with most serfs he’d lived in the commune all his life his parents worked a croft provided to them by the lord, and they were expected to give most of what they harvested to that lord on a seasonal basis. The next homestead was half a mile inland with a family in the exact same situation. Once the lords men left they would have just enough to barter with neighbours with and to subsist on.
He and his little sister were in the forested hills that were a mile behind the house where the sun rose collecting wild plants to bolster dinner. Wild animals weren’t a particular concern as the lords men had killed most of them for sport long ago, a bigger risk was kidnappers but then that was unlikely given they lived on an island. But you never could be sure.
