Clarissa Adler was born to purebloods Jocelyn Adler and Lucian Adler on the 11th of February. They lived in a villa in somewhere in the seaside of England. Clarissa had a wonderful childhood with her parents. Her parents were loving and caring and she couldn't ask for more. For 6 years, she lived happily. Until one day, the fire happened.
What Clarissa didn't know was that her family openly opposed pure blood supremacy and thus were considered as blood traitors. An anti-blood traitor, presumbably disguised as one of the servants since the villa was highly secured, had planned to assassinate the Adlers to 'atone their sins and purify the once-noble family Adler by fire', according to the letter that was left by the embers of the Adler Villa.
It was another normal day in the Adler household. Clarissa and her mother were playing hide-and-seek in their yard and her father was watching them happily from his study. When the servant-turned-assassin saw that the two women were inside the house, he/she immediately casted fiendfyre and escaped through a passage. The fire spread too fast, it immediately reached Lucian's study. Once Lucian was aware of the fiendfyre, he shouted for Jocelyn to escape with Clarissa quickly.
Jocelyn quickly led her daughter outside of the villa and told one of the surviving servants to look after her while she went back in to rescue her husband. But not before telling Clarissa her final words to her; "Don't be sad, darling. You'll see mummy soon. Promise me you'll never be sad." The little girl wiped her tears away, which was useless since tears were still flowing, and nodded.
The servant, maid to be exact, shielded little Clarissa as the villa exploded a few minutes after Jocelyn ran in. Though they were a safe distance from the fire, they never expected the explosion. The maid was badly burnt but luckily had enough energy to Apparate to St. Mungo's. There, she was able to explain what had happened before passing out.
The Healers took care of Clarissa for a while before deciding to take her to Lil'Bundles while the maid was recovering. Unfortunately, the maid was finished off by the servant-turned-assassin, who visited her under a disguise and poisoned the maid.
After a few months chasing after the assassin, the Aurors finally caught him/her and indentified him/her as Maverick Rosier. Maverick spent his whole life in Azkaban.
Meanwhile, Clarissa was just fitting in her new home, familiarizing with the other orphans. She had befriended one particular orphan, a girl named Oliviah.
While out in her little escapades, Clarissa met a young shy girl named Cecilia. Being the ball of sunshine she is, she quickly befriended the girl and played tag with her. Afterwards, Cecilia invited Clarissa to Cecilia's home, in which Clarissa accepted.
After that, Cecilia had made her father promise to adopt Clarissa, which he kept.
