Over on D&D Beyond you can grab a copy of Dragonlance Creatures, the second digital official Monstrous Compendium volume. This volume includes entries from the original Dragonlance Chronicles storyline of the 1980s, such as Dragon Highlord Verminaard (at CR 17!) and his dragon, Ember, along with the Forest Master (the unicorn from Darken Wood) and others.
WotC did the same with Spelljammer, with Volume 1 of the Monstrous Compendium.
