Oh, I totally get what you mean about Birgitte! She’s awesome. For me, I’ve always had a soft spot for Loial. Maybe it’s because I’m a bit of a book nerd myself, but I just love how he’s always so calm and thoughtful, even when things are falling apart around him. Plus, his perspective on everything feels so refreshing compared to all the intensity of the other characters.
And I’ve got to mention Lanfear—she’s technically not minor, but she’s such an interesting character. Her obsession with Lews Therin just makes her pop every time she’s in a scene. Definitely one of the more complex antagonists.
