Probably not. People tend to create ghost stories when they can't explain certain things. In the case of tengah air base, strange noises or lights might have logical explanations like old machinery or natural phenomena, rather than being ghosts.
There could be a whole range of tengah air base ghost stories. It might be that in certain areas of the base, there are cold spots which are often associated with ghostly presences. There could be stories of lights flickering on and off in abandoned buildings on the base for no logical reason. Also, perhaps there are tales of people feeling an eerie presence or being touched by something they can't see when walking around the base at night. These stories are often passed down among the military community or locals who have some connection to the area.
I'm not sure what the specific 'arti chotu love story' is. Maybe it's a story between two people named Arti and Chotu. Without more details, it's hard to say more about it.
There could be characters like Hera Syndulla. She is often associated with Kanan and might play an important role in the graphic novel. Maybe Ezra Bridger could also be in it as he has a connection to Kanan in the Star Wars lore.
I'm not very familiar with the specific love story of Arti Singh and Siddharth Shukla. Maybe they are known in a particular community or context that I'm not fully aware of.
Whether the Kanan comics are canon is a matter of debate. Some aspects might align perfectly with established lore, but there could be elements that don't quite fit. It's not a straightforward yes or no answer.
