Caoimhe Keelan
Personality & Background
Caoimhe Keelan is a muggle-born witch who grew up in Glenvale, a misty Irish village. Raised by her quiet, fiercely independent muggle mother Aisling, Caoimhe never knew her father and was told nothing about him. When her Hogwarts letter arrived at age 11, she devoured every book she could find, determined to learn everything the wizarding world had kept from her.
A proud feminist and a fierce questioner, Caoimhe challenges old wizarding traditions, especially those that diminish or limit witches. She knows almost nothing of her father and her mother refuses to talk about him. All she has is a pen with the intials "ST" on them.
Caoimhe is sharp, skeptical, and driven. She's quick with a question, slow to trust, and unafraid to stand her ground. Though she rarely shows it, she carries a quiet longing to know where she truly comes from, and a deeper fear of what that answer might mean.
True Background
Caoimhe's father was Solomon Thorn, a Ministry agent who worked in the Department of International Magical Cooperation. He spent years tracking post-Soviet dark artifact trafficking rings in Eastern Europe, operating out of Moscow and St. Petersburg. His cover identity throughout was that of a Muggle academic specializing in folklore and mythology — the intersection of Muggle literature and real magic.
In early 1992, Solomon was reassigned to a six-month reconnaissance mission in western Ireland. He arrived in Glenvale posing as his usual cover: a travelling academic researching local Celtic mythology. There he met Aisling Keelan. He fell in love — genuinely, completely. Aisling had no idea he was a wizard. To her, he was a quiet, brilliant scholar who had chosen her small village over the wider world.
When the six months were up, Solomon made a decision. He resigned from the Ministry, stayed in Glenvale, and simply continued living as the Muggle academic he had been pretending to be. It wasn't a cover anymore — it was his life. Aisling knew him as Thomas Keelan — a name he had chosen for himself. Caoimhe was born in November 1992 and took his cover surname. For a few years, they were a family.
When Voldemort returned in June 1995, old enemies resurfaced. Solomon's past caught up with him. In late 1995, when Caoimhe was three, Death Eaters found and killed him. Aisling was left a widow with a toddler and no explanation.
Aisling refused to accept that Solomon had just left. She loved him. She knew him — or thought she did. She began investigating on her own, asking questions, writing letters, searching for any trace of where he had gone. She got close enough that the Ministry noticed. To stop a Muggle woman from stumbling into the wizarding world, the Ministry intervened. They fabricated evidence: forged letters from Solomon to another woman, a paper trail suggesting he had been having an affair and had simply walked away from his family.
Aisling was devastated. The fake letters destroyed what was left of her hope. She stopped searching and never fully recovered. The grief and betrayal shaped everything about how she raised Caoimhe: fiercely independent, distrustful of men who make promises, determined that her daughter would never depend on anyone the way she had depended on Solomon.
When Caoimhe received her Hogwarts letter, Aisling was ecstatic, but also shaken. A witch for a daughter meant Solomon might have been more than he seemed. The old suspicions came flooding back. The affair letters never quite added up. Aisling has quietly begun investigating again, this time armed with the knowledge that the wizarding world exists. Caoimhe doesn't know this yet.
Her wand is Red Oak with a unicorn hair core, 13 inches, and quite yielding.
Story
Caoimhe's first year at Hogwarts has been anything but ordinary. Sorted into Ravenclaw alongside Finlay Figgins and Otto Noxley, she quickly proved herself during a chaotic Potions class when Elias Flint released invisible snakes, earning 100 house points for her quick thinking.
Her curiosity led her deeper into danger. During a field trip to the Forbidden Forest, she and her friends were ambushed by extremists holding Blithe Thimblethorn hostage. When Grimbella Thistlepin arrived to save them, Caoimhe's failed Capto spell nearly exposed the group, but Finlay's quick Infirma Cerebra saved them.
The discovery of a book about Seylon's Tower in The Restricted Section sparked an obsession. Caoimhe masterminded multiple heists, confusing Tamsin Greaves with spells, drugging Callum Vane with Forgetfulness Potion to steal the Dust of Disappearance, and flawlessly impersonating Bixby Wizzlethorpe to fool a half-awake Blithe Thimblethorn. Her sabotage of Miriam's research report secured her team second place in Wizzlethorpe's Research Challenge.
Inside Seylon's Tower, she bonded with a spirited Chinese Fireball dragon hatchling. A portal later transported her to the frozen north, where she met Oleg Mirnov and Katya Mirnova at Frostwell Village. She helped solve the puzzle of the Circle of Eight, only for Oleg to reveal himself as an imposter and betray them.
After surviving a wight's devastating attack, the party pressed deeper into the dungeon. They discovered a ring hovering over frozen water, but when Katya tried to claim it, a water elemental attacked. Caoimhe watched in horror as Katya was dragged under and killed. As the cave collapsed, Caoimhe blasted open an escape route and was lifted to safety by Otto's levitation charm. She lowered a rope to pull up the others, nearly dropping Otto before saving him with a quick Arresto Momentum.
On the surface, Death Eaters ambushed them. Caoimhe immobilized one with Immobulus, but they were caught. After the Death Eaters tortured Otto with the Cruciatus Curse, Aurors Tobias Crane and Rafael Santos arrived just in time to stop a killing curse. Back at Hogwarts, the party was placed under constant escort. June's Midnight Market was shut down after Callum revealed it under questioning.
Over summer, Caoimhe stayed at Otto's estate researching Seylon Vane. She discovered he was Callum's ancestor. When they returned to school, Professor Wizzlethorpe revealed he knew about their adventures and asked them to continue exploring Seylon's Tower, explaining that only children could perceive it for what it truly was. Caoimhe remains deeply suspicious of his motives.
