Firewyre's one of three names I use online - the others are
Bog-fiend and
Tinkergirl.
Firewyre was just because I liked the sound of the word Firewire (the cable) but it was a bit too conventional, so (also liking the very old game 'Bloodwych') I tweaked the spelling a little, retaining the phonetic use.
As it stands, it can sound technical/computery (because of the cable connection), mystical (because of the 'wyre' spelling) and elemental (because of the 'fire'). Very few of these represent me, but it keeps people guessing
Bog-fiend was because I lived in a place in Scotland that had 'bog' in the name (yes, there really was a bog) and randomly liked the word 'fiend' that day.
Tinkergirl was created when I was on a computer game forum because I like being able to tinker and modify with things in games. In mmorpgs and rpgs I play crafters and explorers. And, well, I'm a girl. Frequently misremembered by people as Tinkerbell - grr.
