Alright then, this is what I have managed to recreate so far. I took the opportunity to improve upon it, and I am much happier with the result, though it is still unfinished. Knowledgeable people will notice the many references. 😉
Somewhere, within a vast ocean, countless islands of a great island chain lie scattered and glistening in the dawn. Beautiful and diverse, they stretch across the surface for miles, connected to each other by winding trails of stepping stones left behind from ancient times; when all of the islands were one.
On a subtropical island divided by jungle and grassland, a thick mist hangs in the air, scattering the sun's first rays and lighting the sky like fire. All is quiet except for the sound of the waves lapping against the shore and the vegetation dripping with moisture. Then, as the creatures of the day begin to stir, the silence is broken by a single, lone call. It rings sharply throughout the island, and after a long pause, many other calls follow, each increasing in frequency until soon the island has come alive. A new day has begun.
Within the southern grassland, a cool, open land of sparse trees, many species of animals both great and small roam the tall grass in search of their next meal. The great vined trees of the northern jungle loom over them; a land much more wild and dangerous than its counterpart, and avoided by all but the most adapted and desperate of creatures.
Along the western shore of the grassland, four of one of these species of animals head north through the grass. They are mammals and have evolved over the generations to be well suited for their environment.
