We already have a lot of dragons but we need some smaller ones too. Terrible terror, small shadow or hobgobbler are very known dragons and there whould be no problem with importing them into the game. I think we should be able to have alpha dragons too. Maybe they could work kind of like in rise of berk. They whould be to strong for arena or quests but they could work like the VIP statue. Every 24 hours they whould give runes, fish, coins, eggs, scales or arena points so you can buy some stuff.
