The Order of the Platinum Dragon has just begun their attack on the Halls of the Fire Giant King, but I am thinking ahead to their descent into the depths.
While I am putting together my adventures now in truth I have been planning for this since 1983.
My Giants+ binder was so successful that I am doing the same thing for the D Series and Q modules.
I bought and printed out all the PDFs plus some extras.
Some 5th edition Lolth stats I found on Redit. (I think).
D1-2 Descent into the Depths of the Earth.
D3 Vault of the Drow with the 5th edition conversion from Classic Modules Today.
I am also adding "D4" Encyclopaedia Subterranica from Dragonsfoot.
Then we get into the "Q" series.
Q1 Queen of the Demonweb Pits and the 5e Classic Modules Today conversions.
I am going to add in bits from Skein Of The Death Mother also from Dragonsfoot.
I'll wrap up their underdark/Abyssal adventures with Monte Cook's Queen of Lies, which I am going to mod a bit to make my own Q2.
Been planning this since 1983, back when I went through all of these myself.
It is going to be epic!
