The Mad Mage of Xen'Drik is a tightly-written drag-and-drop adventure location that offers exactly what it says on the tin. Note that this is not a full adventure module, but rather a single (small) dungeon area. While the title might suggest this is only for Eberron, that is not the case. The crazy, reclusive archmage locked away in a tower is seen in all fantasy worlds and thus could be used in the Forgotten Realms or your own setting. The only exception to this is a particularly powerful magic item that is tied to Eberron's planar system and would need a bit of work to fit into the standard D&D cosmology. This is one of the few instances where I appreciate a lower level of context in a D&D supplement.

If asked to pick one sticking point about The Mad Mage of Xen'Drik, it would be that the encounters lack equal attention to the social pillar of play. One encounter toward the end of the supplement has several openings for it, but are not directly addressed by the author.

If you are looking for a classic evil wizard tower, this certainly delivers.

As one of the playtesters for this adventure location, I can attest that it's a TON of fun to play through!
