We have remained tolerant, out of respect for your strength of blood and the character of your family, for too long. What began as a novel, if misguided, experiment has become a haven for blood filth and degenerates. Lumos is a blemish on our society. It encourages misbehaviour, and it sets the children of the great families next to the offspring of Muggle beasts. We have done our best to be patient with you. You have insulted that patience. Lumos should be a resource for the children who deserve it, not a watering hole for delinquent beasts.
Remedy the situation, or the cost will be on your head.
