I am humbled by it's reception, and the three 5-star reviews it's garnered.
"... virtually essential for anyone wanting to create a fantasy world (irrespective for the most part of rule system) who would like to take some of the donkey-work out of it."
-Megan R. (★★★★★)
"Tables of infinite inspiration! Either handpick or randomize the results from these tables to run great sessions with zero preparation! Or use this as a writing aid to create complex, multidimensional adventures, and even use it to develop entire campaign settings! Supplied here is more than enough for DMs to pick from so you can emphasize the details important to you and your group.
I strongly suggest using this along with New Big Dragon's other accessory, the d30 DM Companion. This set is one of the best DM resources I have ever seen!"
-Jeffrey K. (★★★★★)
