I like official lore and the books they have released. I have not read them all, but the ones I have read I liked. I am going to buy the Sylvanas book when it is released next year. I have never read any fanfiction because I worry it might have adult content, and I do not really want to read that.
I do write stories about my own characters within the Warcraft universe, I am not sure if that counts at all. Where the stories are based on my own roleplay, so it is a sort of recap of my own adventures.
I do not post my writing anywhere, nor do I ever think I will. My English is not perfect, so I am not going to want to do that at all.
I do not read fanfiction as I worry of adult content. Not my cup of tea.
Fun topic!
