I am gonna explain my username, and I will also talk about how this accidently became an AU account. Both answers will be separated out so you can skip the AU account explanation if you want!
WARNING: My wanting to yap about all of this makes this whole thing way too long!
How this became an AU account:
If you don't really care about this part since it doesn't answer the question, you can skip it!
Originally, this blog page was supposed to be a casual page to reblog and share art others made relating mostly to TADC. There would have been stuff about my DnD characters and other things I am a fan of as well. There is one post in that spirit, my first post. I shared the song Writing on The Wall, and I expressed how it felt like it could fit canon Caine. I now also feel like it fits for my AU as well.
The second post was the concept post of The (Actual) Good Ending, It was the building blocks, even though some of it has definitely been altered, or just doesn't exist in the AU proper. I had the thought at first that I would only really have a concept post, but I felt inspired. At the time, Episode 8 had recently released, and I felt that Gooseworx would go for a very bittersweet or sad ending. I wanted all the characters to be happy, or at least satisfied at the end, and that happiness being at least somewhat earned.
Even the writing and scale originally was supposed to be just the TAGE story and that's it. Caine was put as the main character, seeking to right his wrongs. Ghost became an idea fairly early on, but her personality wasn't really set in stone yet. Some earlier posts might feel out of character because I was actively developing her as I wrote. I will try to soon have a in universe explanation of why she seemed so out of character in some places.
Curse as a character came in even later, I wanted to have three AIs to be the creations of the three founders. I considered the founders three people that had a pretty large influence. Queenie may seem like an outlier, but with how she treats Caine and Ghost with kindness is a pretty major thing. Her actions in my AU makes her a founder in my eyes. I wanted the fic to be partly about how the founders had influenced their creations. Kinger and Scratch talked to the developing AIs about their feelings. I felt that part would be somewhat of a cautionary tale about why you don't just share how you are feeling to random AIs.
Either way, Queenie and Kinger are now trying to fix the mess that was mainly created by himself and Scratch. Queenie doesn't come out clean since she didn't look for Curse once she knew that the AIs could be sentient. Before I get into the weeds of exploring the plot, which isn't why I am posting this, I will stop myself. I had thoughts on how the story was progressing and followed them. I went along with my improv writing, making sure to come up with either explanations, or things that might bring up even more questions for me and probably the readers as well.
tl;dr for this part: I came up with an AU concept and I just couldn't leave it be. This was supposed to be a casual blog, so the username sadly doesn't have any reference to my AU at all.
-------------------------------
The Answer to the actual question:
I felt an explanation about how this blog became an AU blog somewhat related to the idea of explaining usernames.
As for the actual username, its kind of a mix of different sources. Each word has a different source, so I will explain them. This blog, as I said in the first part, was meant to be a casual one, so the username is based on stuff I enjoyed, or I felt fit.
The first word, cool, is probably the most boring out of the three words. I felt that cool fit because the other two words were owl and rogue. So, cool is being used as a positive descriptor. I think a lot of people would probably find a rogue that is also an owl rather cool. Owl and Rogue have origins that are not as boring.
Owl, the second word, is a bit more personal, but I am willing to share it. I, a long while ago, used to volunteer at a place that had volunteers help care for the three owls they had at the time. I very much enjoyed it, even if it was just cleaning the cage and giving them fresh water and food. They all were screech owls, which by the way, screech owls do not screech, at all. The noises they make I find actually very cute. The attachment that I grew to have with those three owls became rather strong, and I have loved owls ever since.
The final word, Rogue, is related to the DnD version of the Rogue class. I have a character in my current group I am playing with that is a Halfing Rogue. His name is Belfire, and they became a Rogue after signing up to be in one of Eberron's militaries. He became a spy for the military, and learned the languages of those that he was supposed to spy on. He was unable to contact his home during that time because they didn't want Belfire to compromise the missions.
Belfire has not written to his home, or his best friend out of shame. He saw the aftermath of some of his missions, and it wasn't pretty sometimes. He, as a party member tries to find the peaceful option the majority of the time, trying to prevent more deaths that could potentially be on his conscience. After the party lost a newly friended Xvart that was put in harm's way by a fellow party member, he does the rites for them. He catches the eyes of beings you probably shouldn't catch the eye of.
He ends up becoming a Sorcerer along with being a Rogue due to the eyes he has caught. Usually becoming a Sorcerer would be considered a blessing, but not here. Belfire now looks more pale and due to the drain the beings have on him, pulling at his life force, he sometimes feels a bit tired and maybe even kind of weak on occasion. Belfire hoped that resting would improve things, but it never did, this is just how it is now.
His best friend, the one he is actually hopelessly in love with without knowing it, I would argue is more of a badass than he is. She became a Cleric and defending their town, becoming a local town hero. All sorts of people have tried to get with her, but she just can't let go of Belfire emotionally. Hopefully, this idiot that is Belfire finally sends a couple letters so him and his best friend could at least write each other. Could you please, for the love of God Belfire, just write the town and who you are in love with. It doesn't even have to be that long, just tell them you are no longer on active duty, and are, in fact, alive!
You may notice a pattern here, lmao. Yes, all my main characters that I focus the most on, in some way, suck at communication. Usually, they are very intelligent, but there Wisdom stat, whether figurative or literal, really sucks. Here is an explanation of Wisdom in DnD.
I got off track again, so the tl;dr is that cool is a descriptor, owl is from when I used to volunteer to help care of three of them, I grew attached, and rogue is based off of a different character I am tormenting. So, if you think my character not being in the circus means they are safe, you are very wrong.
So, since I am unsure of who is and isn't being okay with being tagged, I will instead say that any of my audience can reblog this that wants to explain their username!
