For me, Lae'zel's story has a lot of emotional depth. She is a githyanki warrior, and her story is full of her struggle to uphold the values of her people while also seeing the flaws in their ways. She has to deal with her own sense of identity and where she belongs in the grand scheme of things, which can be really moving at times.
Wyll's story is also very emotionally deep. He made a pact with a devil to save his city, and now he's on a journey to break that pact. His sense of guilt, his desire to do good despite his deal with evil, and his relationship with his father all add layers of emotion to his story.
I think Lae'zel has a very impactful story. Her strong - willed and somewhat brash personality at first hides a deep - seated sense of purpose. She's from a warrior culture, and her story of trying to uphold her people's values while also experiencing new things in the world outside of her homeland is really powerful.
In Baldur's Gate 3, Astarion has a really engaging backstory. He's a vampire spawn with a past full of abuse and manipulation by his master. His journey of trying to break free from that control while also dealing with his newfound vampiric nature makes for a great story.
Gale is another good one. His story is filled with magic and mystery. His relationship with the Weave and his past mistakes make him a very interesting character to have around during the story. He often provides insights into the magical elements of the game world, which can enhance the overall story experience.
One of the great companion stories is that of Astarion. His journey from being a vampire spawn under Cazador's control to seeking freedom and redemption is really engaging. His past of abuse and his attempts to break free while also dealing with his newfound feelings towards the player character make for a complex and interesting story.
Shadowheart also has an amazing story. She's a cleric with a mysterious past tied to her goddess. As you progress through the game, you get to uncover her true self, her doubts, and her growth. Her story is filled with moral dilemmas and self - discovery, which makes it really interesting.
One of the best companion stories is that of Astarion. His backstory of being a vampire spawn and his journey to break free from Cazador's control is both tragic and engaging. It unfolds as you progress in the game, revealing more about his past and his hopes for the future.
Their personality also matters. A character like Wyll, who is very chivalrous and has a strong sense of justice, can influence the moral compass of the story. His decisions and the way he interacts with the other companions based on his personality can lead the story in different and interesting directions.
For me, it's Vette. Her story as a Twi'lek slave who rises above her circumstances is very inspiring. She has a lot of spunk and her relationship with the player character is really heartwarming. It shows how she grows from a somewhat naive slave to a strong and confident individual.
In my opinion, Lohse has a very interesting story. The whole concept of having a demon within her and her attempts to either control it or get rid of it are really captivating. It's not just a simple 'good vs evil' within her, but a complex relationship that evolves as the game progresses.
I think it's Lae'zel. Her story is centered around her Githyanki heritage and her strict military upbringing. She has very strong beliefs about her race's superiority at first, but as she travels with the group, she begins to question some of those long - held ideas. It's really interesting to see her grow and change as she experiences different cultures and situations outside of what she knew in her homeland.
