Low-level devils like Imps, Thorn Demons, and Whisker Demons rarely have the chance to go to the Material Plane.
If it is a high-level devil, they will search for a Color Pool in the Astral Plane if needed, and travel to the Material Plane through the Color Pool.
As for someone like Rafael, he has a luxurious mansion in the Nine Hells with countless servants, and in that mansion, there's a room with teleportation gates to various cities in the Material Plane, allowing him to come and go as he pleases.
At this moment, Rafael is in the Material Plane, holding a cup of steaming hot tea, standing by the river, admiring the shimmering surface of the water, with a faint and enigmatic smile. He waits for his servant Corilla to bring him all sorts of intelligence, and for when he will need to step forward from behind the scenes.
"Toast me with your gaze, and I'll return the toast with mine..." Rafael is reciting a poem when he suddenly senses his servant approaching.
