The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
..Saw these at my FLGS and was not tempted to buy them. They could help draw a dungeon quickly, if you lacked time to prepare, but I don't think that they are useful enough to justify the purchase.
Helpful if you tend to run games at a whim at your FLGS, after dinner or anywhere else where you don't have a lot prep time. Not really needed of course, but a nice gimmick.
