They returned to the cave, all three of them. Arad, Gojo, and Ice Brood Mother, now called Crawler by Gojo.
While they walked into the cave, Crawler's brider guards split into two groups. One stood guard at the entrance, while the other half spread through the area to hunt for food. Their queen was starved and famished, so it was their job to feed her.
As much as Gojo didn't like having more uncontrolled monsters around, the Yetis on their own were enough of a worry, he was glad that they won't need to go out and hunt to feed Crawler.
Right now, the only somewhat safe brider was Crawler herself, and so, everyone else had to stay out of the cave where the vulnerable Liliana and Haru were. While Arad and Gojo could easily survive an attack from Crawler or almost any monster around, Haru and Liliana were fragile enough to die quickly, which was strange, considering that Liliana was the second strongest person physically here after Arad, thanks to her demonic blood.
