The Art of the Deal

From publisher blurb:

For a level 3 party

There are entities in the multiverse who are engrossed in legend, but rarely (if ever) actually seen. They are the ones who operate behind the scenes, making the common folk question if those whom are deemed most powerful are actually just marionettes; their actions guided by these mysterious individuals. (Un)Fortunately for the PCs, they’ll find themselves at the beckoning of such a being, though his reasons for their inclusion is as mysterious as he.
