Here are some additional facts on dwarves and gnomes:
- Judging by the immense sizes of dwarven strongholds, many of which are now completely abandoned, there was once an extremely large population of these beings. Some of the largest such strongholds could likely have housed millions of dwarves, whereas now most are home only to thousands.
- The one-son tradition doesn't seem to be based wholly on superstition. There's evidence that, in the past, dwarves routinely created more sons and strife resulted. The dwarves refer to this time simply as "the Tumult" and note sadly that dwarves turned against not only each other but also the Makers (the mysterious god-like beings some non-humans revere rather than the gods of Men). Once order was restored, the Makers forbade the dwarves to have more than one son each or dire consequences would ensue.
- The dwarves say that, as bad as having a knocker for a son is, much worse can result from a second or subsequent son carved in violation of the Makers' dictum.
- Unlike elves, dwarves are not immortal. In time, they will revert to the stone out of which they were carved but the process takes close to a millennium for most dwarves.
- Gnomes occupy an odd place in dwarven society, being simultaneously a source of embarrassment, for the line of dwarf with a gnome in it will inevitably die, and pride, for gnomes are what enable the dwarves to create the enchanted items that maintain their dwindling society.
- Consequently, most gnomes are kept hidden away within dwarven strongholds; outsiders rarely hear of them, let alone see them.
- Needless to say, gnomish adventurers are extremely uncommon.
- Many gnomes believe that there is a way for their kind to reproduce and work hard toward finding the means to do so.
- There are many tall tales of gnome-only enclaves in the southern lands, who are self-sustaining after having discovered the means to propagate themselves.
