From publisher blurb:
The Tiny Tome of Dragons is a supplement for the 5th edition of the most popular role-playing game in the world that contains 6 new types of dragons divided into two families. Also, each of them is divided into 12 age categories.
Unlike the normal dragons of the 5th edition, I preferred to create 12 age categories for each of these new dragons, similar to those of previous editions, to have more options for challenge ratings. However, instead of filling the document with statblocks pages, I created a table for each dragon, also similar to the previous editions, but with the most necessary 5th edition stats.
Each dragon also includes its description, the history of where it came from, the description of its Combat style, Habitat/Society, and Ecology. In addition to a list of Actions, Legendary Actions, etc. each of which explains how to easily modify them depending on its age category.
New dragons in this supplement are:
Wilderness Spirit Dragons
Shadowtree Dragon
Wildfire Dragon
Cascade Dragon
Stellar Dragons
Quasar Dragon
Meteor Dragon
Supernova Dragon
