Oscar of Astora is a knight from the Dark Souls series, specifically encountered in the Undead Asylum. He is a noble warrior from Astora who appears weakened and imprisoned, yet he plays an important role as the catalyst for the Chosen Undead’s journey. Oscar gives the player the key and guidance needed to escape the asylum and begin the quest to ring the Bells of Awakening. His brief appearance establishes the game’s tone of fading hope, sacrifice, and the burden of duty.
