A group of reluctant heroes
So, the thing is, I don't really think that it's a problem, just wondering if many DMs have this happen at their tables.
We have a group of PCs. They successfully finished the Rime and are going through VEoR right now. But each of them is still their own person that has a personal plot (family, lover, curse, homeland) that is more important to them than their party.
They clearly care about each other, but since most of their time together was spent "trying to save Icewind Dale/its people/their own lives," they are not even entirely sure that they can call each other friends.
They are not murderhobos or selfish assholes, and they have their own principles, so innocent NPCs get saved and injustice is usually stopped. It's just that none of them are like, "I'm so happy to be here with you guys, this is the best part of my life, and I've always dreamed of adventuring with a great party like this." They are more like, "I would really like it if we defeated Vecna fast, because there is a civil war in my motherland / I'd like to get back to my coup in Neverwinter / my revenge on the Order of Blue Fire is awaiting me / I am vital to the process of rebuilding the influence of the Order of the Gauntlet in Bryn Shander / etc."
So, does that happen often to you guys? Do you feel like it's a bad thing?
