Vanligga has to pay taxes in The Fremennik Islesquest, although the player has the option to pay them for her. By doing this she will open her store, Contraband Yak Produce, which sells various illegal yak goods. A player may also pay 5000 coins to her after the quest, if they did tax her.
"Vanligga Gastfrihet" may be a pun of the Swedish proverb "Vänlig Gästfrihet", which can be translated to "kind hospitality". It could also be "Vanlig Gästfrihet", which can be translated to "Common hospitality".
