Learn About Final Step

Journal
''I brought the Frostgeist Hexe Core to Esmeralda in the Highvale Outskirts monastery. She took it, ground it up, and threw the powdery essence in my face. Supposedly, now I can use another looking-glass to travel across the area. I want to finish this investigation, so I'll ask her about the "final step" she mentioned.''
