This is a super rad book! The new species are really intriguing (there's a species of huminoids who have evolved from WHALES! You can be a whale!) and the worldbuilding is really unique and has my brain full of ideas for my campaign! There's enough here to run an entire campaign in this setting but I run an existing campaign and I'm excited to make a weird hybrid monster from this & eberron. There's tons of creatures and lore that can easily slot into my existing campaign. The art is super pretty and I plan on printing some out to show to my players. Most of the NPCs are gay. Your warlock patron can be a kaiju. What more could you want? Five stars.
