Here’s the headcanons in question:

* Thorn is the main songwriter of the trio
* Thorn's actual name is Sally McKnight (like in the Witch's Ghost)
* Luna, aside from being keyboardist and bassist also has a talent for painting and is the designer for their album covers 
* Dusk is the youngest of the trio and is also thr most rebellious and the least mature of said trio as she has a rather quick temper and a violent tendency, is always the prankster of the group (she'd be the most likely to pin a 'Heave a rock at me' sign on someone's back), has a superiority complex, even willing to break the law and overall the most likely to start trouble. Though she does have a good heart deep down.
* Luna, despite being the calmest, has a rather snarky edge
* Luna and Dusk often butt heads, as Dusk is the kind of friend who often pressures Luna into doing thing they shouldn't, which leaves Thorn, the most level-headed of the trio, to reel them in and act as the 'team mom' of the trio
* Dusk, aside from being a drummer is also skilled at boxing and playing basketball
* Thorn is the outdoorsy type (of course, to love the earth IS her one desire)
* All three of them are big fans of Vincent Van Ghoul, ESPECIALLY Thorn (who even has an autographed photo of him)
* All three of them have known each other since 1st grade
* Also like in Witch's Ghost, Thorn's father is also the pharmacist and is very supportive of her career 
* Thorn's mother died when she was still in kindergarten and was also a musician and singer, which is where Thorn obviously got her musical talent from
* Dusk is a huge fan of the Blue Falcon
* Thorn has a secret crush on Scott Pilgrim which she covers up by pretending to hate him, which Dusk often teases her about
* Dusk has mild ADHD
* Luna's father is a dentist (also like in the Witch's Ghost), and her mother is a yoga teacher and school counselor
* Dusk has a rich mother who she has a love/hate relationship with as she often disapproves of her daughter's career yet they do care for each other deep down (similar to how the Mystery Gang's families act towards them), and she had an abusive father (which is where her above-mentioned fierce tendencies stem from) who was split from her family when she was younger
* All three of them were fans of Josie and the Pussycats as kids, which is partially what led them to starting a band.
* Their manager Gus Boggs acts as a pseudo-fatherly figure to the three of them (á la Jerry from Totally Spies!), and even often cooks and/or caters meals for them.(Though he and Dusk often butt heads)
* Luna has OCD
* Thorn was a fan LazyTown and The Wiggles as a kid and secretly listens to their music when she's alone
* Luna's secretly into classical music
* Dusk is into sensitive guys (I ship her and Shaggy BTW)
* Luna secretly has a crippling fear of clowns
