I'm sorry, I haven't actually read a novel specifically named 'northern grand duke hamster novel'. It could be a very unique or perhaps a self - created title. It might be about a hamster in a northern region that has some sort of grand or noble - like status within the story.
It's hard to say exactly. But it might involve the hamster's adventures in the northern territory. Maybe it's on a quest to find something important for its hamster kingdom.
If you accidentally click on the "reduce" button on the volcano video, you can try the following methods to recover:
1. Re-open the volcano video client and try to view the selected work again.
2 If you can't view the selected work again, you can try to find the "application" option in the "settings" of the volcano video and then choose the "volcano video" application and try to clear the buffer and data.
3 If you still can't restore the selected work, you can try to contact the customer service of Volcano Video for help.
If the above methods still cannot restore the selected work, it may mean that the work has been deleted by the volcano video and cannot be restored. In this case, you may need to find other resources to read the work.
The duke is obviously one of the main characters. There might also be a female lead who has some sort of relationship with the duke, perhaps a love interest or a character who challenges him. Other possible main characters could be the duke's family members, like his parents or siblings, who play a role in the story's plot and the duke's development.
The fate of Duke in G.I. Joe comics is not consistent. Sometimes he perishes, but different writers and story arcs handle his character's fate differently.
