Reward: 4000 Renown.
Follow the direction pointed by the golden dot on the map until you reach the village of Snowspire, where you will meet Scythe in person. He will tell you about the only way to solve the Summoners problem - to wake the Oracle up and ask it for help. You will need to know four magical gestures in order to do that. They are hidden on magical glyphs somewhere in the Necropolis. Head that way.
You will have to search through the whole region, searching for the three glyphs buried in randomly chosen graves. The last one in at the western end of the map, you will have to battle the Snow Troll to get in there (a worthy opponent, you will have to dodge his homing ice missiles and try not to get blown away too far). Once you have all the glyphs, get back to Snowspire. You will have an occasion to have a little chit-chat with the Oracle.
From this moment you can use one of the 4 newly acquired expressions to talk to the Oracle. You can learn some interesting and funny stuff that way.
