Duskfire Glacier Racing ahead, into the light

Posting a conclusion.

The new parents were full of questions, and Tzila would no doubt answer them to the best of her knowledge, putting both the expectant mother and nervous father at greater ease.  

With Tzila and Rye at her side (as unlikely as a trio as that may be), Lane would enter the Greyfall Caverns and judge each chamber until the perfect one was found. Around every bend, Lane would try to visualize what it would look like for her pups to be nestled in this nook or that cranny. Thank God for Tzila; she had a good eye for spaces and several times urged Lane and Rye to keep looking, even when they thought they'd found a good spot. 

In the end, it was Tzila that found the beautiful central chamber, with light streaming in from a crack in the ceiling above. It was perfect. The mothers would dig their individual rooms off of this communal chamber, and eventually all of their pups would be able to socialize in the sunny, communal playroom.
