Coming up with my username was a long and strenuous journey.
I had a lot of try-hard usernames in the past based on what sounded cool, such as Unknown Master, then Final Radiance (which derived from Last Shine which didn't last long), then Radiant was the name I stuck with for a long time.
I started getting into deep Wii hacking, and got pretty jealous of most prominent member's unique usernames (like Waninkoko, crediar, etc) so I REALLY wanted a unique username.
I also wanted it to be short and simple, without the need of "xX*_MASTER^GAMER_*Xx" or numbers because bleh2typical4me.
At first, I did the "cool word" thing again, using the word "Continuum" and made it into "Muuni-Tnoc" which is obviously backwards. It sounded nice but it was kinda lame and confusing at the same time, so I decided to look for random words and their translations instead. Looked through Japanese (which I thought after a while ended up really generic and typical to see on the internet, and I'm not that big on the culture to begin with) then I went to German, Italian, and most words I used sounded pretty similar to their English versions so that idea then ended rather quickly.
Then finally I decided to pursue something unique to the heritage I am, which is Colombian. As with every race or culture, there was always legends or myths, so I decided to look into Colombian mythologies and found the "Musica Mythology".
Reading through, there were plenty Spanish sounding words which were neat but I decided since most were so small, I'd look for two that sound good together, but a few caught my interest,
"The gods created the first materials of the universe: Fiva (the air), Faova (the cosmic cloud) and Ie (the smoke). "
Ie was removed since it was too short, so I stuck with "Fiva" and "Faova", I put them together, and since "Faova" was a less appealing sounding word than "Fiva" I made it second, removed "Fa" and switched "ova" to "voa" to make it sound smoother together, and here we are today.
This name, on Google, only show results of my stuff to this day. :D
