What is dark angels?

Dark Angels is the name of a fictional chapter of Space Marines in the popular tabletop game Warhammer 40,000. They are one of the original chapters of the Space Marines, which are genetically-engineered super soldiers created to defend humanity.

The Dark Angels are known for their dedication to secrecy and their obsession with hunting down their own traitorous members. They also have a strong connection to the Fallen Angels, a group of Space Marines who betrayed the Dark Angels during the Horus Heresy, a major conflict in the game's lore.
