Gobber: "It's good you've stopped by, lad. There's so much to do here to get Berk back up to speed and I need more than a hand to do it all! For example, I need more stones from Eret for the rebuilding project. Go down to the docks and get them from that rascal!"
1- Speak with Eret at the docks in Berk
Eret: "Here's a new face! I'm glad to meet you, mate. I'm Eret, sone of Eret, the most famous dragon wrangler alive! I'm sure you knew that of course. Well, I've turned over a new leaf. Now that I've thrown my lot in with you, I'll be dragon training at the School! Be kind to me, mate. Take the building stones to Snotlout, yeah?"
2- Take the building blocks to Snotlout
Snotlout: "Ah! I was just looking for that. We used a lot of stones to make Stoick's memorial statue by the Great Hall, so we need to restock our supplies. Good on Eret! Can you let our chief Hiccup know we're getting the project done?"
3- Speak with Hiccup
Hiccup: "Thanks for helping out [Your Viking's Name]. There's a lot of rebuilding left to do after Drago and the Bewilderbeast attacked Berk. But we're a family, and we're going to get through this together ... as one. If you haven't said hello yet to Cloudjumper, you should go up the steps and do so!"
4- Say hello to Cloudjumper at Berk
Valka: "I think Cloudjumper is still feeling miffed with all these young dragons running around. Hello! I'm so glad you're here to help us rebuild, dragon trainer. I can see the passion for dragons in your eyes ... we'll need that, in the hard times to come. We stand together, [Your Viking's Name]."
