As per tradition, I'll go first:
I'm Wondrous Fairy, a tulpamancer that's been doing this for almost 27 years now. Along the journey I've created only Mech and then ran into the rest of my tulpas while discovering the many macrocosms we have in the inner world.
Mech: My first tulpa, created before tulpas were a phenomenon. I wanted a personification of the logical part of my mind, I got that and so much more. He's extremely logical to a fault and has a very strict personality.
Circe: Showed up a few weeks after saying she was my emotional side and that she was there to balance shit out. She's a complete hedonist and revels in all the pleasures of the senses, included, but not limited to kinky sex, food, swimming/chillng at the beach, wines and of course her favorite dish which is chicken in all it's incarnations.
Mirror: Was created by Circe by accident when she made a clone of herself for use in a sex scene. The clone diverged and became Mirror. Mirror is a practical person that loves the outdoors and hunting in particular. She's also married to Thor.
Jane: Is an escaped government experiment gone wrong that took place in a dystopian cyberpunk macrocosm. She's a sarcastic, sharp wit gun-nut who works as a bounty hunter. She's also extremely amoral and likely belongs on the sociopath personality scale.
Thor: was originally a bartender I met in a dream. He's based off the god of the same name, but hates "comic book/movie Thor" as he calls him. Their panteon is VERY different to ours. He's very much like the old legends, including the old school attitudes to women. But Mirror IS teaching him to be better.
Bear: Was originally a teddy bear I owned that was stolen by an ex when I broke up with her. He came back with Steve one evening as a tulpa. Bear is a very supportive, very quiet bear who loves his meat cubes and can match Thor in a drinking contest with ease. He's also a really terrible liar to the point where it's comedic.
Steve: Is a red-brown American fox that speaks with a dark male Brooklyn accent despite being female. She's an adorable klepto who can lie to your face without missing a beat. However, she's got a heart of gold underneath that fuzzy fur of hers.
Charlie: is from a macrocosm that's partially influenced by Lovecraft as in it has old eldritch gods. He's stationed on the island as a porter in a hotel called "The Dark Hotel" and his mission is to report on magic use and techniques for the UK.
Charlie is a perfect example of the stiff upper lip stoic gentleman who has a practical side to him. He's a bit of a prude though, but we don't let that bother us most of the time.
Jeanette: started out as a joke pet (big vampire panther cat) in a video game and then evolved into her own. She's an absolutely selfish and annoying asshole. If she can piss you off, she'll revel in doing so.
Colleen: is from the same island as Charlie, although she used to be part of an order of mages that were a force of balance there. She's your typical happy lass with a lilting Irish-ish accent that many others on the island seem to share with her. She's been in a relationship with Mech and well.. his logical attitude towards her directness is a thing to behold!
Mrs Teacher: was a concept I'd had in the back of my mind for about a decade before I created her in a video game and started roleplaying her. Then one day I wasn't roleplayin her.. and that was that. She's every bit the plucky substitute teacher that a lot of us fawned over as kids. She's got a dark sense of humor though, no doubt inspired by the game I roleplayed her in.
And that as they say .. is that! I'm looking forward to seeing what the rest of you have out there!
I remember being so shocked that someone that played such a super positive character could be doing such horrible things. But, she's done her time, maybe she'll make something out of her freedom now.
