Yan-C-Bin

Yan-C-Bin (pronounced yan-see-bin) is the Prince of Evil Air. A being of great wisdom and malice, Yan-C-Bin's plots began at the forging of the worlds. Subtler than the other elemental princes, Yan-C-Bin operates unseen, studying his enemies from afar, ambushing them swiftly, and vanishing before his foes can retaliate.

His natural form is an invisible vortex of howling, swirling air 30 feet high and 15 feet wide, but Yan-C-Bin sometimes takes the shape of a gaunt, venerable, dark-skinned human with wispy white hair and glowing white eyes. When he wishes to remain unseen, Yan-C-Bin manifests only as a gust of cold wind flowing silently past.

From his floating palace in the endless, cloudy skies of the Plane of Air, Yan-C-Bin watches worlds as they change over millennia. Evil aerial creatures worship the elemental prince as a god, and claim to see Yan-C-Bin's eyes in swirling storms. Yan-C-Bin doesn't care for their offerings, their sacrifices, or their worship. His only concern is the annihilation of the material realms as they are ripped apart by the superior elemental might of air and wind.

Yan-C-Bin's Lair

Yan-C-Bin dwells in a palace of air on the Elemental Plane of Air. In his palace and in air nodes on the Material Plane (including the Howling Caves, described in chapter 5), Yan-C-Bin is master. He can use the following actions in his lair.
