The "Underdark Legends" series mentioned by the Gnoll chieftain was actually a print publication recently created by the God of Gambling to spread his glory and gambling games throughout the Underground World.
As everyone knew, even the perilous Underground World held countless buried treasure chests.
Since many treasure chests were hidden in unknown corners, treasure hunting had even become a distinct profession in the Underground World.
In densely populated areas and chaotic underground cities, people often fought fiercely over a single treasure chest.
After all, given McKen's standards, the things hidden inside treasure chests were likely treasures capable of changing a person's fate for life!
The Treasure Chest God's renown in the Underdark was second only to the Ancient Gods slumbering there!
In terms of devotion, those cunning casual believers underground might even have been more willing to believe in McKen.
After McKen left, Qin Lele, as his Chosen One, took control of some of the treasure chest permissions.
Whether she had done it deliberately, hoping to use treasure chests to establish an entirely new media channel, or simply acted on a whim because she wanted to have some fun, she had, intentionally or otherwise, created a highly popular print publication.
This was "Underdark Legends."
"Underdark Legends" often appeared alongside treasure chests. After several previous rounds of distribution, it had already received widespread attention and praise throughout the Underground World.
Though the magazine Underdark Legends appeared to mostly record the geography, customs, legends, and absurd myths of the Underdark, the gambling advertisements woven throughout were Qin Lele's true objective.
But the unintended effort had borne fruit.
The residents of the Underground World were instead more interested in the anecdotes and information included in the magazine.
That was hardly surprising. The Underdark had always been a place with extremely poor communications.
