The interior of the giant mahagony tree was hollow and ringed with stairs that looked like they were part of the tree itself. Hanging lights that looked like fruits dangled from the stairs.
Of course since the tree was pretty much vertical and there was a hollow shaft in the middle, Kire simply chose to fly up to the top of tree instead of taking the stairs. Thanks to his high flight speed, he reached the top landing in only a few seconds. He then walked up the last staircase and found himself inside a sizable room. The floor of the room was grass and lighting was provided by several of the same wooden lights that lit up the stairwell. Flowers and shrubs grew out of the grass. A shimmer dark green crystal floating above a plinth made of a variety of lush plants was the centerpiece of the room.
"Ah, Kire, what brings you here?"
Kire turned to see the speaker, a young woman dressed in nothing but some leaves and vines. "We just arrived in the jungle after an underground expedition, Chryseis," he replied.

The letter that Stripetail had received had its wax seal still intact by the time Stripetail opened and read it.
I had received a note from what appears to be a Pinkstone aligned operative at around lunchtime. As my lessons were done for the day, I took a group of volunteers to the location mentioned in the note. Upon entering the location, I encountered what seems to be a cell of anti-Ministry insurgents calling themselves the "Society for the Abolishment of the Statute of Secrecy". They offered to assist us in capturing Chong but they also stated that we would need to reciprocate. I would like to discuss this turn of events with our group further. However, due to the sensitive nature of this discussion, this must occur in person."
