I'm not sure who exactly 'rc' is without more context. But 'rc' could be anyone. As for the stories, they could be of any genre like adventure, mystery, or fantasy.
This question involved many different novel settings and plots. Different novels might have different answers. However, generally speaking, the possibility of the Shadowman taking the Crawler was very small because the Crawler was usually a very powerful creature, and the Shadowman usually had to rely on his own strength to survive.
In some novels, the Shadowmen might use some special abilities to attack the Crawlers, such as using dark powers or magic to destroy the Crawlers 'base. However, in other novels, the Shadowmen might not risk attacking the Crawlers because they knew the Crawlers 'great strength and defense. They might choose to cooperate with other creatures to survive.
In short, there was no definite answer to this question. It depended on the specific plot and setting of the novel.
Maybe the stories by 'rc' have unique characters. They might be very detailed in their descriptions, whether it's about the settings or the characters' emotions.
