Something wicked

This quest is gained by talking to Ser Otto in the Elven Alienage. After finding to pieces of evidence, return and he will unlock the orphanage. It is advisable to save multiple times because this area has a tendency to glitch. Do not skip the cutscenes or else you may be locked in the room with no exit after the initial fight with the rage demon. If this happens, talking to Ser Otto may trigger the cutscene once more.
