Fundead is a supplement that presents cool new systems for creating fey undead. A drow mage is presented in the text and a fun, creepy backstory is provided for the creation of these magics. Aside from the NPC, this supplement contains two new spells and a new magic item targeted at creating fey undead, as well as several sample creatures. The creature design is clever, combining the strenghts and weaknesses of the source creatures in interesting and fun ways.
Fundead is conceived as a sister release for Simon Collins' The Sylvan Harp, but neither product requires the other to function. Having read both, I must say I do think they compliment each other perfectly.
And with the price tag, the value is through the roof. HIGHLY RECOMMENDED!
