What's the story behind your username?
If you are one of us folks whose username is not your actual name, what is the story behind it?
I'll go first.
Amarth was an evil necromancer character I made for a very old "rogue-like" Tolkien-based PC game Angband, and later on a similar necromancer in Diablo 2. It's been my recurring gamer name since back in the days.
It was picked at a whim while I were browsing through Tolkien's Silmarillion and it simply means "Doom" in Sindarin. Most famously in Amon Amarth, Mount Doom, the volcano where the One ring was forged. A fitting (though admittedly silly) name for a necromancer.
Now as it happens I'm from Sweden and there's a somewhat famous Swedish death metal band named Amon Amarth. So everyone thinks I took the name from them and that I'm a fan, though neither is true. I simply took it from the same original source as them - Tolkien.
I took my username from one of the characters in the John Knowles novel, A Separate Peace. Loved the book when I read it, as a teenager, and admired the character Finny/Phineas. We both have the habit of passively listening to what is going on around us while focusing on something else, then replaying/recalling it later. Anyway, whenever I tried to sign up for something online using Phineas it was always taken, so I spelled it Phyneas and the usernames were generally open, so it stuck and I've been using it for almost everything (online) ever since.
Fell in love with Black Library books ever since they started making em a long time ago... Fell even more in love with the works of Dan Abnett. His Inquisitor trilogies, Comics, Titanicus book, First and only series etc. is what makes me come back for more and more. One name stuck with me ever since I read it first time "Cherubael". So that is when I started using it as my nickname on the internetzz... As time passed by and my brain cells evaporated Cherubael became Cherubel.
The SS part of my username is the abbreviation of my real name.
The numeric part
3.1415926535897932384626433 is the value of ratio of circumference to diameter of a circle. In reality, this value is infinitely long, but I had to trim it down to 25 post-decimal digits because of the limitation of Stack Exchange. I picked this ratio because I was always interested in it. Also, there's a supernatural kind of thing attached with it. When I was kid, I realized I already knew certain things like speed of light is fastest. The value of ratio of circumference to diameter of a circle being infinitely long was also among them.
The entire username signifies that the mystery of SS is infinitely long just like ratio of circumference... oh, leave it.
