You were stranded on an island in a desolate world, with your memories intact. You had nothing to start with or nowhere to go. You tried searching for any other soul but failed. You then started to explore for any hidden ruins or food. But to no success. You spent the whole day walking around the island, and you were really hungry. Eventually, you encountered the ruins of a temple. You decided to explore it in search of food. To your surprise, you found a strange black book inside the temple, which was locked in a drawer under an alter of a moon goddess.

I read the book.

As you read it, a dark energy flowed into your body. The book also glowed. The energy was strange, and it was not like any other magic energy that you have ever experienced. You felt it coursing through your body, and a strange sense of familiarity came upon you. You felt that in the past, you have read this exact book! You opened your eyes and saw that the book had the same dark markings as the energy that had flowed into you.

I test my dark magic.

Your dark magic has the ability to summon things from your imagination. As you imagined a fireball, a fireball appeared at your fingertips. You also thought of how powerful magic you could use, and the dark energy responded with power matching your imagination. You then tried conjuring an army of skeletons, and they appeared at your command. With your power at maximum, you could summon a city at your whim!

I summon something to eat.

You suddenly get a craving for steak. You imagined your favorite steak, and it appeared on your table. You started eating it. As you ate it, it tasted as real as possible. Suddenly, an idea came upon you. You imagined yourself having an endless amount of any luxury, and it appeared at your command. You could have anything that you have ever desired in the palm of your hand. With your powers, you could also create any weapon that you can think of. With your infinite power, there is nothing that you cannot overcome!

I leave the temple.

You leave the temple with your power at maximum. You were eager to explore this strange world. There are so many possibilities with your powers. You could even create your own country. You could control the world and be the King of the world. You could travel among the stars and create your own Empire among the stars! You could become the God of this world? Who knows….
human
Maybe,  in time. But right now I just wish to explore this world.

You were extremely eager to explore the world with your powers at maximum. You were eager to find out everything that this world had to offer you. You left the ruins and started entering the forest of the island. You then started searching for any settlement or civilization. After hours of searching, you finally found a small settlement, and you decided to enter into it. You then entered the village. You were extremely lucky, as this looked to be a rather prosperous settlement. There were many people in the settlement, and it looked to be a rather advanced civilization.
