When Arad walked into the main hall with Alga still in his arms, he could see Isdis and Eris sitting around a large table with a few tens of angels, talking about the ongoing constructions. They all seemed too busy, but from what Arad could see, all of those angels were ones he had seen in the private quarter before, the same ones who worked on Eris's heaven. They should be able to lead the construction with ease.
For now, they didn't notice Arad due to his draconic presence masking his existence alongside Alga, who was in his arms. He didn't want to bother them while they were working, but he had to get Alga settled in as quickly as possible, so he took a step out of the shadows.
When Arad's foot landed on the ground and his presence became clear, it was as if the entire hall plunged into darkness, and everyone immediately glared in his direction, horrified that he managed to sneak up on them like a ghost. "Isdis! I'm back with her."
