𝑬 𝑨 𝑹 𝑳 𝒀 ● 𝑳 𝑰 𝑭 𝑬 | Alasdair was born into a respected pure-blooded household on what muggles believe to be the ruin of Lochindorb Castle in the Scottish Highlands. His father, Cathal Comyn, is a scion of the famous clan Comyn of Badenoch, a line of aristocrats that rose to prominence in wizarding society when they faked their extinction to avoid muggle persecution following their feud with clan Bruce over the Scottish crown during the kingdom's first war of independence. His mother, Thusnelda von Tschirnhaus, is the last-living descendant of the Silesian branch of the Tschirnhaus family. She is a direct descendant of Ehrenfried Walther von Tschirnhaus, a pure-blooded wizard whose talents in alchemy introduced porcelain to Enlightenment Europe. Their union had been an arranged one, as both families harboured strong sentiments for blood purity. Despite the fact that they first met at the altar, Cathal and Thusnelda managed to build up a functioning, uncontroversial relationship, which was rather unorthodox and clinical insofar that the two never shared public displays of affection, which suited the family's stiff and stoic identity.
His early childhood was marked by his family’s immense privilege and affluence. The Comyns and Tschirnhauses had both built up considerable generational wealth, which meant that Alasdair grew up without any wants or needs. Despite his material comfort, the pressure to succeed in life weighed heavily upon his shoulders - he would have to fulfill the expectations and duties his family had thrust upon him, or spend his last days penniless, knowing that he had been unable to preserve his family’s century-old fortune.
Alasdair tried to remedy that stress by applying himself physically; his sister may have been more adept at using magic, but he would be stronger, bigger and faster. As he grew up, he became absolutely obsessed with quidditch, and tried to set up a fan club for The Prides in his native Inverness-shire, which his parents quickly forbade him to do, as they regarded fan club memberships as a gauche, plebeian pathway to hooliganism.
Nevertheless, Alasdair remained exceptionally interested in quidditch, and spent a lot of his time trying to stay up-to-date with game results, league standings and player transfers. He stuck to supporting the Pride of Portree, his local club, and frequented their home games, especially when they played the Montrose Magpies in the Highland derby.
Besides staying physically active and obsessing over quidditch, Alasdair accompanied his father Cathal on days out hunting nogtails and other pests on the Comyn estate. The two share very fond memories of wandering the length and breadth of Scotland’s moors and glens, which instilled a deep fascination and respect for nature within the young Von Tschirnhaus-Comyn.
In what remaining spare time he had, Alasdair attended balls, galas, banquets and charity fundraisers with his family. Armed with his extensive knowledge of social etiquette and a certain quick wit that he cultivated to out-do his twin sister, the young scion felt right at home at these events, delighting in the many compliments he received on his immaculate manners and courtly behaviour.
