Analysis of information sources in references of the Wikipedia article "Cain and Abel (comics)" in English language version.
In The Sandman comics, Cain is invulnerable, and he and his brother were sent to live in The Dreaming thanks to Morpheus' invitation. They also might not be the literal Cain and Abel from the Bible but abstract archetypes of the first murderer and first victim. The characters' appearances almost always end with Cain killing Abel once again.
Cain and Abel are not how you remember them from the Bible, but that's because they're not Biblical references, they're comic book revivals. The two were the Cryptkeeper-style hosts of DC Comics' EC-imitating horror anthology series, House of Mystery and House of Secrets.
