Your name, or, at least, what you have named yourself, shall henceforth be Hecticles. (The color shall change as you act in this world. For now... how about a cool grey?)
You reach out towards the supernova, attempting to take the gift you have been promised. At once, you feel its power coursing through you, the flames seeping into you, within you, until they become a part of you, as natural as a hand or a nose.
At once, you perceive your new gift as a bright blue flame. It surrounds you completely, and that is when you realize you have no body. The supernova in the distance begins to shrink, as your gift forms a new (or perhaps, your first) body. You may describe it if you wish, but all the same, the brilliant lights fade from view, and you swim in darkness once again.
You open your eyes, and find that you have been dreaming this entire time. Standing up, you perceive you are within a dry, almost barren grassland. Only a few bushes and decaying trees are at home here. Towards the west, you can see the markings of human civilization. To the south, you see the grassland become more vibrant, though not by much. In addition to this, to the east you see the land become populated with more hills, and you believe you can spot a cave. To the north seems to be a group of lions and lionesses.
Ah, yes, and you are also still on fire. Though, strangely, the fire seems to be protecting you, as if shielding you from whatever deadly assassins may try to take the life of amnesiacs that dream in the middle of nowhere. Or perhaps it's protecting you from the air. Either way, it doesn't seem to be harming you, at least.
What shall you do now, Hecticles?
