Roland's world thus far was a small one. For some time it did not extend past his mother. Her smell. The feel of her fur against the soft sensitive leather of his nose. The warmth of her body and the taste of her milk. It gradually extended from there as the sun rose and fell time and again. First he became aware of a gloom just past her body as his eyes opened. Then he came to know of a light past that gloom, and his nose began to detect a few more scents. Roland soon after acquired a sense of hearing, soft and muffled as it were, and so then could be aware of the world in a new way.
His body developed alongside his awareness. His growing strength allowed him to explore this expanding world and be part of it. He became able to move from his mother's side and was able to stay warm even if she left him for a while. The den walls he now knew. The light however he stayed away from. Not until his eyes were able to handle it better. Not until they were able to see through it. Roland came to realize that his sharpening eyes were revealing to him another world beyond the light, just as they had revealed the light beyond the gloom earlier on.
Curiosity drew him closer. But it took the boldness that had been bubbling in his mind to finally rise to the surface of his psyche and stir his paws up the slope of the den until his silver face poked beyond the entryway. Here he sat on his rump and lingered squinting into the sun. By the same instinct that kept him close to his mother the warmth gradually drew him out. His steps were tentative and he went no further than a few lengths of his own body before he stopped and sat again to observe his new surroundings.
There was much to take in.
