A burden in the hands of parents who found themselves too financially unstable to care for him, a very young Holden found himself at the mercy of the orphanage. This was where he spent the first couple of years of his life, often minding his own business and keeping to himself, quiet as a mouse while he observed his surroundings, never becoming completely used to or happy with them. Each day went by with Holden hoping for freedom, and with each day that went by, he found himself losing hope more and more, until one day. A witch and a wizard by the names of Roderick and Brigitta Schmidt visited the orphanage in the hopes of adopting a child. Needless to say, upon seeing Holden, their household almost immediately gained a new member, the two taking to Holden almost immediately. In his new home, Holden felt more content than ever, though he hadn't completely adjusted yet. Over the years, he began to become more aware and comfortable of the world surrounding him. During this stage, Holden was informed by his parents that they were expecting twins. He was ecstatic at the idea of there being someone around who he could potentially have things in common with, as well as who could understand him.
With the arrival of the twins, Holden slowly began to come out of his shell. Countless playful arguments with his sister Keira as well as numerous exchanges in acts of kindness with his sister Ilsa raised his confidence in his family as well as his security, and he'd never felt so positive regarding the matter of family, clearing him of his constant guilt as well as building the foundations of the person he is today.
At the age of 11, Holden was sent to Hogwarts School of Witchcraft and Wizardry, being sorted into Hufflepuff. For once, he felt alone again, having to be away from his family and muggle friends for so long, having to wait for years before being used to them in a similar environment again. It felt like having to start from the beginning all over again, everything he'd worked so hard to sustain feeling pointless.
However, his arrival at Hogwarts wasn't completely negative. Traits from both his mother and father began to rub off on him over the years - his father's Quidditch career prompting an interest in flying and quidditch, while his mother's academic talents in turn led to his academic success. Holden went through a rough patch during his first few years at Hogwarts, only really letting himself go during holidays when he could go home.
Though it took some adjustment, Holden took to independent life, his frame of mind having been seemingly strengthened by the time he spent at the orphanage years ago. On top of this, he started to establish friendships just like he did in his school before Hogwarts. Things were finally looking up for him, especially with his two sisters joining Hogwarts a few years after him.
As his time through Hogwarts progressed, he turned into a complete social butterfly, something which he'd never have thought possible before. The playful banter with his sister Keira forever continued as she got older, as well as he and Ilsa's kindness towards each other. In his sixth year, he played as a beater for the Hufflepuff Quidditch Team, becoming a staple of the team for the year, but deciding to resign in his seventh year to study for his N.E.W.T's.
Having passed his N.E.W.T's with flying colours, Holden entered the real world, having moved into his own home, not having overly great ambitions - just something enjoyable which he can use to provide for himself. This led to him becoming the owner of a café in the muggle world, as he always enjoyed muggle interaction and very much misses it. Though recently, though the air of guilt and resentment which seems to only exist in his mind has haunted him, feeling like he was nothing but a burden to his parents, though there's been nothing to give him this idea. To this day, he's still too troubled on the topic to inquire.
