From the stories and legends of the elders is understood that some of the villages of the commune have their own legend.

A legend says that the territory between Gura Bascei and Valea Lungă, Buda, Lăpuş and Tisău, were in the possession of two brothers and a sister. The two brothers entered into conflict with Mrs Neagă and were sentenced, the earth due to them being confiscated and given to some monks. The sister ruled the estate from Iazul Crucii to the west of Viperești and Izvorul Putna to the east of Viperești. It is said that this was bad like a viper, hence the name of Viperești.
Another legend says that the name of Viperești comes from the existence of a large number of vipers in the forests of the commune. The third legend  says that  a great nobleman was coming from Ciolanu monastery in a chaise, and next to Lacul fără Fund a viper came out in the way of the horses that were pulling the chaise, they got scared and the nobleman with the horses and the chaise fell into the lake and have never been found. The people who have told this story named the place Viperești.

Tronariul has its name after the occupation of the people to make  „thrones” out of wood, that is some crates of plank, beautifully and skillfully carved, in which the girls kept their things for dowry. Such thrones are also found even today, but currently the people use them in the household to store grain.

Rușavăț village has its name from the nobleman Rușavețeanu, good man in the area, which helped the community to develop by building the church and the school to which had access also the children of the people that were working his land.
