General emphasis on smells in sense-descriptions. My notes follow (page numbers from 1993 Baen printing): However, with this read-through I was paying more attention to lesser-known, possibly overlooked tidbits, that either are or could be used as core parts of our game. Most of us are aware of the big-ticket items: Alignment (the cosmic system of Law-vs-Chaos prior looks one, two), the paladin with a holy sword, a Scottish-speaking dwarf, and the swanmay (see also: mythological swan maidens).

I recently re-read Poul Anderson's Three Hearts and Three Lions.
