Santa is, lamentably, no more.
Nicholas Flamel, long time associate of Albus Dumbledore, was the eponymous "Saint Nick."
Born c.1330, he would go on to achieve the creation of the Philosopher's (Sorcerer's) Stone in 1382, which conferred upon him practical immortality and limitless wealth.
He used his riches to acquire a significant number of the world's House Elves, and a Time Turner. He would then enchant reindeer to give his sleigh flight. An accomplished legilimens he could discern the naughty and the nice while they slept.
Over the centuries his legend grew. But, with the enactment of the 1689 International Statute of Magical Secrecy, he was obliged to end his beneficence.
He transferred his House Elves to the Hogwarts and Beauxbatons Wizarding schools. He lived on, in relative seclusion, in Paris until his death in 1992 after the Stone was destroyed as a precaution against its' misuse.
It is rumored that the only time that Albus and Aberforth Dumbledore could endure each other's company was at Nicholas' Christmas dinners, until much later in life, where they each partook of an aperitif of The Elixir of Life.
