Valiant Comics was created in 1990.

In the "Prince Valiant" story, Sombelance is a villainous knight who appears in the early comics. He is known for his cruel and deceitful ways, often causing trouble for Prince Valiant and his companions. Sombelance is eventually defeated by Valiant and his allies in a series of thrilling adventures.

well, the valiant comics take place after the adventure of link, which is the last event on the fallen hero timeline. Also there is no information about what happened after that. So because this is the only information we have about the events afterward, you could say its non-canon, but again, we don't know what happened, the comics could be totally wrong. I guess it just depends on how you look at it.

Marvel Comics has been involved in various exchange deals with other comics publishers over the years. Some notable exchanges include trading characters with DC Comics in the past. Additionally, Marvel has collaborated with companies like Image Comics and Valiant Comics for crossover events.

I know that I've seen it in "The Birmingham News" here in Alabama.It's been in every Sunday issue in the comics section since I was a child.
