Hiccup: "We are sending out our fastest ships to find new dragon training recruits, but the fog is too thick for them to travel. People who live in normal places can wait for the fog to lift... but this is Berk. It's always foggy and cold.
1- Meet Mulch by the school lake
Mulch: "Fishers depend on the position of the sun and the stars to find out where we are and how to get to our destination. When the sun is gone, we're more confused than blindfolded Gronckles!
Hiccup: "Now that Mulch mentions it, I've heard of Vikings using a sunstone compass to help navigate deep fog. Let's try and make one. One of the main parts of the sunstone is an Iceland Spar, a rare transparent calcite crystal.
2- Find the Iceland Spar in the Wilderness
Hiccup: "What a find, [Your Viking's Name]! That's going to fit perfectly in our device!
3- Deliver the spar to Hiccup
Hiccup: "This rock is perfect for our compass!
4- Get wood pieces from Bucket
Bucket: "How about these broken pieces off my old boat? I don't know if I can make something good out of it, so you can have them. You can use one for the top and one for the bottom."
Hiccup: "We need to get some metal to hold them together. I bet the blacksmith will have some to spare! Go see Gobber in the Hatchery."
5- Talk to Gobber in the Hatchery
Gobber: "Sure, I have plenty of nails you can have for your little project! I don't have any on me right now.
6- Collect 3 pieces of metal from Gobber' house (0/3)
Gobber: "Those will do, [Your Viking's Name]. Those will do.
7- Meet Phlegma at the Lookout
Phlegma: "Nice to see you, [Your Viking's Name]. I'd be glad to give you a few gears, but you can never get something for nothing. You'll need to do something for me!
8- Catch a halibut at the sea
Phlegma: "That looks mouthwateringly tasty!
9- Deliver the halibut to Phlegma
Phlegma: "Here you go! I'll make sure to let the Headmaster know who caught this delicious fish!"
Hiccup: "Great! Now that you have all the parts, we can put this sunstone compass together."
10- Deliver the parts to Hiccup
Hiccup: "I'm really excited that it's finished! Let me tell you how this works. You place a do to the top of the crystal and then look up at it from below!
11- Play a Flight Club course
Hiccup: "It's a great feeling to fly through the sky on your dragon!
12- Collect the compass from Hiccup
Hiccup: "This has to be one of the coolest inventions ever! Please bring it to Mulch in Berk. I'm sure he'll be glad to have a solution to the fog."
13- Deliver the compass to Mulch
Mulch: "You and chief Hiccup are quite remarkable. I will get this on my fishing boat and have Bucket start spreading the word to everyone."
