They kept on walking through the forest, at times talking with each other, at times silent to admire the wonders of the nature around them. After a while, Valerion came to a sudden stop; he bent down and sat on his haunches - "Look", he said, "Chestnuts". Adrien scanned the ground, and for a couple seconds he saw nothing but dry leaves; then he noticed a spiny chestnut bur camouflaged among the leaves - and then he realized that the whole forest floor was peppered with these burs, their fruits appearing in slivers past their barbed shells. He looked up, and saw that they were standing underneath a massive chestnut tree - doubtlessly a hundred years old at the very least, judging from the size of the trunk.
