I was furious to hear the story of these two Elves, from what Sophia said they were on a mission to escort a merchant, but having bandits infiltrated the crew they were poisoned and couldn't even fight to defend themselves.
While waiting for Elsaris to come back I talked to Sophia to ask some more questions, I soon found out that Julius was about to retire and was just doing some missions with Silvio to help him.
But it looks like now he won't be adventurous again, he said he's going to retire and take Silvio back to the village of the Elves, from what Sophia said it's the same place where she lived, so she's going to write a letter to her acquaintances that Julius will deliver on your behalf.
