Hajovy dzied (literally — "grove grandfather") or Hajun is a woodland spirit. He protects his grove, maintaining order. Every animal and bird in forest obey and serve him.

The head of Hajun is like mans’ but his hair is of silver moss. The rest is spitting image of bear that walks on two rear legs. There are some places in the wood, which Hajun loves and cares for them the most that no one would touch it's untouched beauty. If anyone tried to chop the wood there, Hajun appears before trespasser in his true form. Naturally, after that no human has set foot here for a long time. But sometimes a real tragedy occurred, when Hajun in anger fell a tree down at woodcutter before he alerted and scared him.

In earlier days no house was built without Hajun’s approval. It was widely thought that the house built with Hajun’s approval will be firm and durable. To get this approval the owner of the future house went in forest with gifts. He put gifts somewhere on tree-stump and said: “Here is the treat for grove grandfather. Eat it by yourself or give to your granddaughters” (granddaughters of Hajovy dzied are hajoŭkі). If Hajovy dzied takes the treat, it means that he agreed. If the next morning gifts weren’t found it meant that the place for cutting wood had been chosen right. In some cases gifts lied where they were left. It meant that other place has to be found. There were some cases when people chose wood and began to build a house without permission of the Hajun. In that case Hajun seeing mischief sent to a house a rabbit showing by it that house won’t stand for long
