Finally, Some Food!

I was running out of supplies. Fast. If I didn't find another island soon, I was a dead man. After all, what was I going to do? Drink the salt water?
Luckily, I soon came across another island. Even luckier, it was the most abundant island I had seen yet. Unlike the desolate Ismara, this island was covered in green pastures, and was a taste to my eye after leagues of salt water. I immediately landed on the beach and headed deep into the island, looking for food.
I soon found what I was looking for: a gigantic flock of sheep, all grazing on the grass. Fortunately, I had brought cooking utensils and a gun with me, in case I ever needed to catch my own food. I quickly shot one of the sheep, dragged it away, and began making a fire to roast it. The roasting was taking a long time; it still wasn't done by the time the sun went down. I had to stay up, of course, and wait for my dinner. However, barely five minutes after the sun set, I heard a thunderous roar in the direction of the flock of sheep I had left behind. Were there nocturnal predators on this island? I had been so obsessed with getting food that I hadn't put any thought into it; but now that I am alone in the dark, that becomes a very scary thought.
I will set this journal down for a second, until I figure out what the noise is. This may end up being my last entry, for all I know.
