By the time came when I have to find an elf and I am in the process of recruiting Cornelio, I killed the first elf that I saw just outside his house. Mediocrity was thrown at me but even if I killed Cornelio, I was still able to "befriend" him. Based on the some guide over at GAME FAQs, you have to use the rune to "collect" the elf. Is this correct? Will I have to really find other elves to secure Cornelio as part of SOD?
