I'm loving this book in one light, and cringing at it in another. There are so many awesome, unique niche details that are given full light in this book. You can build the most perfect, individual snowflake you want using this book, and have it all be perfectly above board and canon... and that's the weakness of this book. With all of the tools provided here, you could make yourself a Demon worshiping, half-fae, abyssal mystic with necromancy, and naturally developed blood magic... all without stretching.

This book is like a one ton block of salt. It's great to supply decades worth of meals, but if you dropped the whole thing in on one meal, it'd ruin everything.

I plan on taking pieces of this into my games and characters, sprinkling here and there. I highly recommend that any ST that allows this as canon require a thorough review of how their players use the lore.
