After taking a ton of screenshots and failing to get an answer from Pnimm, Ajact, or either of your guardians, you decide to investigate the weird building while your screenshots very slowly upload to Filebin. You'll need to get in eventually, after all. The only problem is that there doesn't seem to be an entrance of any kind. Maybe there's some way to climb up? It looks like there are windows on the dome up there, and they might be large enough for a second moult to squeeze in.
