It's been really interesting to read about origins and stories behind the usernames... after reading so many, I figured I'll share mine as well.
So I have 2 usernames I kinda rotate around... One is 'avendora' and the other one is 'Vedova' - the one I use here.
The first online game I started years and years ago was 'Astrowars', a real-time online strategy kinda RPG. At that time I was reading the 'Wheel of Time' by Robert Jordan. Avendoraldera has an important part in that story, it is a cutting from the Tree of Life, Avendesora. It is said that these Chora trees emit a sense of peace and relaxation for any who pass below their branches. After my first round in the game (every round takes around 3 months, then starts anew), I took on the role of the diplomat more often than not, (you form ingame alliances and there is a lot of strategy and 'diplomacy' involved in planning your end game strategy) so I changed my name to "avendora" - which has been one of my usernames ever since. I got more involved in the game, acted as admin on the forum, participated in coding game related tools... my name was kinda known over time - sometimes a good thing sometimes not so much. In pre-planning of yet another round, we decided to go undercover, no ties and chance of revenge on old foes, but without them knowing it's us. Since we decided on zero diplomacy and full out war, I figured the opposite of 'life' would fit well - and as a symbol of death, but just as natural as the tree of life, I liked the idea of 'Black Widow'. Since I tend to pick latin names, it ended up being 'Vedova Nera', and over time was shortened down to 'Vedova' or just 'Vedo'.
