So we know he had a battle bear, and he wont talk about the subject to anyone. There is a legendary called Venebinium Root (or something) that drops healing items when you sprint. The description is done by boldur, it says “poison, poison, poison, NOT poison.” and that you should NOT mention this root around him. He also has a garden.
So what happened to his bear? I’m wondering if he accidentally poisoned him by giving him the wrong root, something he thought was Venebinium to heal him from a battle injury.
Or i’unno, bear died of old age? Boldurs thousands of years old.
