Elden Ring contains numerous NPCs that will give you side quests to complete throughout your journey. Unfortunately, Elden Ring does not contain a quest log or map objectives to track these quests so it can be hard to know which quests you’ve started or even how to finish them.
Irina is an NPC you will meet at the entrance to the Weeping Peninsula, just past the bridge of Sacrifices. She is sitting by the main road that leads to Castle Morne. Speaking with Irina, you will find out what has been happening at Castle Morne, located further down this main road, and of her father, Edgar, the Commander of Castle Morne. Irina will ask you to deliver a letter to Edgar if you find him at Castle Morne.
Where to deliver Irina’s Letter?
Castle Morne is located at the south end of the Weeping Peninsula—be wary of the giant wielding a bow guarding the entrance. Upon entering the castle you will need to head through the courtyard, and past the praying demi-humans to a ladder leading up to the ramparts. Follow this path, being careful with the two flying demi-humans, and you will see another ladder to the left. At the end of this path, Edger can be found sitting atop the tower.
After you have delivered the letter and exhausted Edgar’s available dialogue, you will need to defeat the boss of Castle Morne, Leonine Misbegotten. Once done, return to Edgar and let him know that his duty to protect the castle is over.
Go back to Irina
Return to Irina, just past the Bridge of Sacrifices to complete this quest. Edgar will be here and offer some attentional dialogue. Irina’s quest end here though, but Edgar will offer his own quest for you to complete.
