What are the characteristics of Elrond?

Could you please elaborate on the distinct features of Elrond? I'm particularly interested in his personality traits, abilities, and his role within the narrative. How does he differ from other characters? Is he known for his wisdom, bravery, or perhaps a unique skill set? Also, how does his background influence his behavior and decisions? Would you say that he's a proactive or reactive character? I'm eager to learn more about this intriguing figure.
