Back on Vaenor Report

General Summary

They plan to head back down to get the rest of the loot. Some damp cloths and holding their breath later, they manage to get all the items and coin. They spend the night on Mawise and leave in the morning.
Everyone keeps working on their projects despite the bad weather along the way and arrive on Vaenor 2.5 days later.
Sandor receives payment for the bags of ParaNip, Ratchet and Flind look for the Maskarran hideout which is another brothel, and the other hire some horses. The captain of the guard comes up to them and delivers a message from Lady Billberry. Apparently Velsharoon set sail for Dara'Thica after killing Amyntas and he demanded some Dwarves to come with him to Grimsthad.
Arriving in Myth Vaenor in the evening, the city is quieting down. Suiv's brother tell them his mom hasn't been out of the grove much and only his sister is allowed inside, since she is a druid. Just then queen Elora appears behind them and seems glad that they have arrived. She reassures them she is fine and they can afford to spend the night in peace. Suiv's father is gloom and misses his wife very much.
The next day they head for the grove and Elora keeps the way open for them. The entrance to the tree has been opened and thus P'N'S enters...
A room, 40 feet across, with a spiraling elevation broken up by branches and natural bridges heads up. In the center, on the floor, is a big hole covered in spider webs. Looking up they notice more webbing surrounding a ring only reachable by climbing some vines.
What will this tree hold and what's down the hole?
