Loftwings and Demons

So since the sequel trilogy darksiders aren't Sith, I got to thinking about their aesthetic, and what kind of holocrons they would have.  And I thought, well, maybe they'd want a different shape from the Sith, so not pyramidal.  And the Jedi took cubes already.  And so I thought--what about spheres?  That would be fun, right?  Holocron doubles as a sports ball when the Knights of Ren are on break.
