How does your character communicate with others over a long distance? Do they write letters, send texts, write words in the sky, use a crystal ball, just teleport to meet in person...? Draw or write your character using their preferred method of sending messages.
How does Bertrand communicate with overs far away. The traditional way, of course - classic pen and ink. Yes, one needs to be careful not to smudge or spill the ink, and it does take a while for the letters to reach the reciepient, but that's how it was always done in his family.
