What to do about the Stone Ghost?

The heroes performed a final meticulous search & healed up a bit before bringing this important information back to the Magaambya. They found 3 more magical masks, along with some expensive rugs hung on the walls. Gazzean & Orkbolt found a secret stash in the wall, but could find no sign of a seam to open. Argent leaned on one end of the stone, breaking it open with a claw. Inside we found more magic! While we took some time to rest up Orkbolt identified some of the magic items. Afterward, we went to investigate the last bits of this area that we knew of, using the new maps we had just found. We encountered a Gray Ooze. It was a little tough, but not too bad. Then we found where some of the Gremlins had been mining. They had thrown down their tools and obviously left in a hurry. We looked down one of the tunnels they had been mining, finding a backpack partially buried in the rubble. Gazzean managed to get it free, but not before the rubble shifted, crushing some of the contents. The other 2 tunnels held nothing of interest. The last room we had not explored turned out to hold 3 fake Giant Centipede traps. We defeated/disabled them and headed back to the Magaambya.
We found Teacher Ot, handing over our findings, along with the notes and maps from the Stone Ghost. Teacher Ot told us to go home and rest up. He requested we give him our full notes the next morning. We spent the rest of the day divvying up & selling our loot. The following morning we returned to speak with the teachers. After we explained our findings, he told us that Teacher Coraday felt that the insects may have been drawn to the Magaambya by an artifact, the Vesicant Egg. Teacher Coraday does not even know if this item exists, only having heard rumors of it's existence. He did not want us to invest any time in trying to track down this artifact. As our conversation was finishing up Esi came bounding up saying that some new students were waiting to meet Teacher Ot. She said they were 3 Anadi. He asked if we would like to come along to meet the new students. We agreed. We met with the new students. As we were welcoming them to the Magaambya 3 Griffons swooped in to attack them. Teacher Ot put up some sort of invisible barrier to protect them while we dealt with them. Afterward, Teacher Ot took them to the dorms while we headed to see about getting our gear upgraded with some of the runes we had found. Teacher Ot requested that we meet him at Noon.
