Your realm
Your realm is your own island with a heart. It grows with your quests: workshop, garden, forge and portal court appear one after another (tiers 1 to 4).
Quests that ask you to "hand in at the heart" are completed with /dragon heart at the heart.
Only you and your members may build or use doors and chests. Invite friends with /dragon invite or let them visit with /dragon visit. Back up your island with /dragon snapshot.
