The Whispering Hillock

Something about life in dreary backwoods settlements leads their inhabitants to hide the truth with misleading names. This takes the form of both hyperbole - a clump of bare trees called "Dragon Spike Forest" or a hole in the ground two paces deep named "The Chasm of Eternity" - and understatement - a horrid massacre calmly referred to as "the incident." Velen fit the mold in this regard, as Geralt learned while he wandered through it in search of Ciri. There he encountered a trio of highly suspicious magical sisters called the Ladies of the Wood, who directed him to a clump of bogside huts known as Downwarren. Geralt was to solve their "problem": a rash of mysterious murders. He spoke to the ealdorman and learned that the evil power behind the killings dwelled in the Whispering Hillock. Wherever else?
