The first part of Underfoot's "Unfolding the Lore" series is out and centers around Brell's Rest:

Brell's Rest

Brell's Rest is the place where the worthy of Brell's worshippers go when their time on Norrath ends. Some worshippers are given places amongst those of the Underfoot, to work on the world, but few find such a thing to their liking. Many spend their afterlife in an "ideal" setting for their race. Dwarves, gnomes, gnolls, kobolds and others all live in or around Brell's Rest or in the Shining City just out of sight on the sphere above. However, most of the residents of the Rest are gnolls and kobolds. The dwarves tend to stay in the city brewing beer and crafting things in stone and metal, while the Gnomes tinker, though some of them also wander the land to see what's up out there.

There is much conflict between the gnolls and kobolds in this domain, since conflict is what they love. Their violent and destructive tendencies tend to keep them out of the Shining City.

There is also an arena dedicated to battle in Brell's Rest. Here groups of warriors challenge each other to games to prove their superiority.

Trouble in Paradise

Gnoll and kobold warriors have clashed joyfully on the battlefields of Brell's Rest for millennia, but recently the kobolds have found fewer sparring partners. The gnolls have been acting stranger and stranger, as though they are hiding something from the rest of the realm. Most aren't speaking at all, but those who do will only whisper of one they call "The Destroyer" or "The Undying One," their faces twisted by equal parts fear and adulation. Whoever or whatever "The Destroyer" is, the gnolls do not appear to have it under their control just yet.
