"So, what happens to a shard of a demi-god that rolls along the inter-twining energies of life and ends up as a, more or less, whole being?"

Perhaps the best description of what that is will be given from the thing before you, the appearance as you gaze abruptly is as follows

Name ( Yes, you can see it) : I
Last Name: Non-existent (Feel free to ponder or ask why)
Gender: What? (Really?)
Height: 6'~ (Changing on off days from 5'-ish to 7'-ish)
Everything else: Mostly not there

A closer look will give you
The thing before you isn't exactly a man or a woman or... anything, now is it? It's more akin to a piece of armor. Some kind of helmet horror, only it isn't, is it?
Who in the Nine Hells below and Seven Heavens above knows?
All you get from this being as you gaze is this: "I".
You have no idea why, how, and where from. It's just the letter, the sound it makes, or the ideas behind it.

If you gaze into the void below whatever the being wares, you'll notice infinite. Is it a void completely with darkness, or some manner of star-streamed look into the night's sky
Well, that's really up to you, isn't it?
What is your "I"?

Though, in the end of the day, "I" is just like any other person (Probably not like ANY other, yet he, or she, or it, still holds to its opinions) and will probably give you a good time whatever you're doing or thinking.

Lights:
The character is silly, the player is also silly. Figure it out yourselves.
