Hello,
1: Defeat the boss at the top of Solitude Peak.
2: Go find some cookies by clicking on Karen's doghouse in Horace's house in Feasterra.
3: Then give the cookie to Karen who will give you a key.
4: Go to the Gents of the Glory Dungeon (at night), open the cabin and use the key on the Lens extractor.
5: Use the item on the telescope on Grant's bedroom balcony.
6: Use the same item on the telescopes which are placed above the Grant's fireplace.
7: Place the lens on Ghart's telescope and look through (at night only). Note this should be the Ghart's telescope (the viking) and not the Grant's one.
8: Leave Whellcum (at night) and a new place named "???" will be present on the map (be careful, it is only present at night).
9: Arm yourself with the Dragon sword and wake up the sleeping dragon.
