There are two characters on offer here. The first is a Sorcerer with a couple interesting mechanical bits and bobs (new spell and shaping ritual). However, he's ultimately nothing special, and even his best tricks are going to be fairly useless as a challenge for even starting PCs. I don't just mean in combat, here. I mean he's a total pushover and will be a mere speedbump in any contest with a party of Exalted.

The second is a generic information broker who stepped out of a generic 80's fantasy novel. He's bland, he comes with no itneresting plot hooks, and his stat block could be created by a novice ST in about ten minutes. He doesn't even have the virtue of neat mechanical bits and bobs. The only challenge he will pose for PCs is the debate about whether to simply beat information out of him, or scare him half to death with a single intimidation roll.

To call either of them "adversary" is disengenuous at best. Give these a pass unless you are really hard up for NPC ideas.

The two beasties provided in this booklet are simply not worth the money. The Ghost's dice pools are quite high for its purpose, and the Behemoth will probably destroy your average PC Circle of Solars. The Ghost is an easy fix; the Behemoth has interlocking mechanics that make fixing it a tear-down job.

While I'm all for tweaking material to suit a group's needs, these diverge significantly from the material and tone with the rest of the game, and I don't think it was worth the money. I can find plenty of great ideas on the internet for free and then pour hours into the mechanics.
