One could access the grimoire network from within VR-Universe through their VR-Saferoom and other functions but that would not be possible when they enter the dungeon. For that to be possible Wyatt would have to host the entire grimoire network in this personal-realm network just like how he hosted the VR-universe in his personal-realm network. Since the VR universe was hosted in his personal realm network, he and others could use the VR universe inside a dungeon.
