3. Match the appearance and personality
Use the creation options available in the app to give your character a recognizable look and personality. Keep these choices consistent with the identity: the same mapmaker should still feel like the same person across a profile, conversation and shared creation. Use original material or material you have permission to use.
A small idea to get you started
Start with a curious mapmaker who lives among floating islands. Give them one interest, a way of speaking, and a question they like to ask. Then test how those choices feel in a conversation.
