In the 1930s an anonymous publication concerned with preserving the purity of bloodlines within the magical population was compiled, giving a compendium of the truly pure-blood families with 'the aim of helping such families maintain the purity of their bloodlines'. The so-called 'Sacred Twenty-Eight' comprised the families of: Abbott, Avery, Black, Bulstrode, Burke, Carrow, Crouch, Fawley, Flint, Gaunt, Greengrass, Lestrange, Longbottom, Macmillan, Malfoy, Nott, Ollivander, Parkinson, Prewett, Rosier, Rowle, Selwyn, Shacklebolt, Shafiq, Slughorn, Travers, Weasley, and Yaxley.

The Avery family was one like any other in the 'Sacred Twenty-Eight', known for their status, their wealth, and their fanatical devotion to pure-blood philosophy. Victor and Agnes Avery raised their children to uphold the same beliefs, twins, Ines and Oberon. The children were the epitome of pureblood children. Pure in every sense of the word. Ines had learned about the witches and wizards before her who had abandoned the lives they had to live a life and abandon their purity. She never thought that could be her until she met a boy named after the stars who made her want to forget of her namesake entirely.
