Third paragraph under Born of Deep Earth:

Svirfneblin are well adapted for their subterranean existence. They have excellent darkvision, and many of them have magical talents that rival the innate spellcasting of the drow and duergar. They are surprisingly strong for their size, enduring toil and
danger that would overwhelm most other people.

First paragraph under Deep Dwellers:

Svirfneblin are known as deep gnomes because they choose to live far below the earth’s surface. Most svirfneblin never see the light of day. Their homes are well-hidden strongholds concealed by mazelike passages and clever illusions. Vast networks of mine
tunnels ring most svirfneblin settlements, guarded by deadly traps and concealed sentries. Once a traveler passes through the outer defenses, the tunnels open up into marvelous cavern-towns carved from the surrounding rock with exquisite care. The svirfneblin are austere in their comforts compared to their surface cousins, but they take great pride in their stonework.
