The Caretaker is a minor villain in the Witcher 3: Wild Hunt DLC Hearts of Stone.
The Caretaker was conjured from another dimension by Olgierd von Everec to serve his wife Iris as well as to take care of the Everec estate and to kill any intruders. After the death of Iris, the Caretaker continued to serve and killed anyone who tried to enter and loot the abandoned mansion. He buried the bodies of those he killed in a makeshift graveyard near the gardens.
When Geralt enters the mansion to find Iris von Everec, he meets a bandit whose friend had entered the mansion and not returned. He then catches a glimpse of the Caretaker but he is immediately hidden by the fog surrounding him. Geralt enters the gardens to find the missing bandit but is attacked by the Caretaker.
In battle, the Caretaker regenerates part of his health with every hit he lands. Also, he conjures the spirits of those he killed in order to slay them and thus regenerating health. He also uses otherwordly magic to launch energy waves at Geralt.
After having slain the Caretaker, Geralt is able to enter the mansion.
There are more things in heaven and earth than are dreamt of in philosophy.

The Caretaker served with the indifference of a golem, and proved as fierce in battle as it was diligent in its labors. It felt no pain – in fact, each blow it received seemed to give it strength, as did each blow it landed on Geralt with the spade it wielded as a weapon. What is more, the Caretaker was able to summon powerful spirits from the graves it had dug and could heal itself by absorbing them. The witcher had a hard time evading the devastating strikes of its weapon, and his only chance at wounding the creature came when it would stick its spade in the ground to draw on otherworldly energy in an attempt to petrify its foes with fright.
