Does your online name come from the elemental fiend from FFIV, or did it come from another source?
It actually has two sources!
First is the Divine Comedy - which as a very silly 14 year old I thought was the coolest shit ever to use as a means of teaching myself Latin. (It was not)
Then there's the fiend Rubicante from Final Fantasy 4 - which was my introduction to the series as a whole. After battling my way through the Crystal Tower for the first time, I was very taken with a boss that was polite and gracious enough to heal me before kicking my arse and promptly landing me near the beginning of the tower once more.
If you're curious as to why I'm "Rude" Rubicante - it's because I'm not nearly so gracious.
And I swear a lot.
