I don't care when you make this house, or if you make it at all-- I just thought it would be a super fun idea! Here goes!
Well, first off, thanks so much for Wintertusk... I love it, a lot. I really love Nordrilund, it is so full of intrigue! I love how it is so contrasted, how there are rivers of lava and then a block of ice or an ice sheet right next to it. In my opinion, I think it would be super fun to do a Nordilund themed home, with lava and ice and the like as a yard. the main house should be a cave, perhaps? I don't know, I just thought a home that was entirely based around a cave would be fun. It could have a web of tunnels and caverns, or just a couple large caverns, I don't know... it's just a suggestion.
You of course don't have to do it :P I just thought it up when I was in Nordrilund. Maybe it could be crafted, or maybe it could just be bought somewhere.
