I feel like all good Dark Souls fans have their own personal favorite characters they've interacted with over the course of the series, and it's always interesting to hear exactly why those respective characters stand out.
As for me, I feel pretty trite in saying I pinball between the trio of Solaire, Knight Artorias, and Dragonslayer Ornstein, three of the most obvious and beloved characters from the first game. But, particularly in the case of Artorias and Ornstein, the mythology surrounding these characters has always fascinated me, offering enough intriguing gaps in their individual histories to leave me curious.
Whether because of lore or the simple joy of interaction, who are the characters you always think about when you think about Dark Souls?
(P.S. -- I was set to make this a poll but wow, wow, wow there are a lot of Dark Souls characters.)
