It's your first day as Center Realm's official cartographer, and you've already got a big problem. Center Realm is home to three elder dragons: two ice, one fire, and they've lived in harmony for centuries. But scouts have sighted three fire dragons and five ice dragons flying towards the region. Can you figure out where to place the new dragons? Henri Picciotto shows how. \[Directed by Igor Coric, Artrake Studio, narrated by Addison Anderson, music by Cem Misirlioglu, Greg Chudzik\].
