Thanks guys! I see that all of you have leveled up to level 5 on DNDBeyond, so thank you for that!
Due to the shift in interest from Silver Flame cult/city surface stuff to dungeon-delving and planes-hopping, I am going to take about one week to design the megadungeon, and work on the discoveries there. I was not expecting to go this route; the game kind of naturally moved in that direction, which I am happy with, but need some time to prepare. I need to figure out which maps I want to use, and determine what other giant secrets you will encounter and how those will affect this region of the world.
Please let me know if you have any questions, thoughts, or concerns, and thank you so much for your willingness to go on this journey with me!
