Arjun overheard the conversation and decided to contribute to it. 

"Our numbers have been growing quite a bit, Kut- er- Alexius." He made a mental note to use the newer name. "Our hatchery is still full, and I've been sure to, er, help contribute to that." He spared the others the details. "Apart from that, we've been opening up some new caves. We've discovered a new batch of hot springs. It's really helped now that the old ones were getting overcrowded." 

As they walked, they could see kobolds from the tribe scurry about. Some carried ore in brown sacks slung over their shoulders. Others held baskets of food foraged from the nearby caves as well as meat brought in from hunting in some of the deeper caverns. A few even carried fish caught from subterranean rivers.
