Power Lich

"Power liches? Sounds dangerous. I don't know if these power liches. If they do, probably this would be dangerous I think. They could protect the Haunted Estate, so as to make me scared about this..."

--Su Ji-Hoon, The Strength of the Liches

A power lich is the upgrade to the lich, the fifth-tier creature of the Necropolis faction in Heroes of Might and Magic III. It can be recruited from the upgraded mausoleum.

In When the Cold Breeze Blows Away, they work in the Haunted Estate as well.
