I wish I could make permanent companion. I would not think that most npc would be interested in doing so. Also I don't want a servant but a partner. I imagine a give and take relationship through intermittent quests like I wish to see my family, or I want to spend the day fishing, I like that Njerp's spear can I have it? With the consequences being some like "That's fine that you do not want to return to my home I'll go alone. I hope our paths cross again someday friend"
