The main characters in 'last voyage novel' could vary widely. It could be a family who is on the last voyage together, with each family member having their own goals and fears. There might be a scientist on board, studying some unique phenomenon during this final journey. Also, there could be a conflict - driven character, like a rival sailor who causes trouble during the voyage.
The central character is Dracula, who is on board the Demeter. He is the one causing all the mayhem. The crew of the Demeter are also main characters in a way. They experience the horror first - hand. They start as normal sailors but are gradually terrorized by Dracula. For example, the captain who has to deal with the strange happenings on the ship and the sailors who try to figure out what's going on and ultimately fall victim to Dracula's thirst for blood.
There might be a young and brave sailor as one of the main characters. He could be the one who first discovers the strange things happening on the ship during the last voyage. Also, perhaps an old seaman who has some knowledge about the ship's past and might be able to give some clues about why it has become a 'ghost ship' now.
Often, there will be the sailors who discover the ghost ship. They are the main characters as they are the ones who experience the events of the last voyage.
There might be a captain or a navigator as main characters in 'Voyage in the Dark Novel'. The captain would be responsible for guiding the ship during the voyage. And perhaps there is also a stowaway, someone who sneaks onto the ship and then becomes involved in various events during the journey. This stowaway could add an element of mystery and conflict to the story.
I'm not sure specifically as there could be many novels with 'last voyage' in the title. It might be about a final journey, perhaps of a ship or a character, which could involve themes like self - discovery, adventure, or facing the end of something.
There might be a female character who is an expert navigator and joins the voyage with the pirate king. Also, there could be an old sailor with a mysterious past who has some important knowledge about the destinations they are headed to. The pirate king would be the central figure, around whom the other characters revolve. He might have a loyal crew member who has been with him for a long time and acts as his right - hand man during the various escapades.
I'm not sure specifically as it depends on how the visual novel is developed. But it's likely to have the protagonist from the original 'Voyage to Brobdingnag' story, who travels to this land of giants.
Since I haven't read the book, it's difficult to say who the main characters are. But based on the title, it might be a traveler who embarks on the voyage to Panjikant. There could also be local people in Panjikant who play important roles in the story, like a village elder or a young person with a unique perspective on the place.
I don't have specific information about the main characters in it. But typically in a story about a great voyage, there could be a brave captain, a skilled navigator, and a group of diverse crew members, each with their own skills and personalities.
Since we have so little information, it's impossible to say for sure. However, common main characters in voyage stories are often the captain, who is in charge and has to make difficult decisions. There might also be a young and adventurous crew member who is on his first big voyage and has a lot to learn. Or perhaps there is a stowaway, someone who sneaks onto the ship and causes all sorts of unexpected situations during the voyage.
