Mantol-Derith is supposed to be a neutral outpost in the underdark, a place where all groups can meet without threat of violence. Unfortunately it didn't take much for all of that peace to fall apart...

We need to make it to Mantol-Derith to uncover more details about the situation, but first we need to solve the problems that are causing this all out inter-faction war!

Note: you will need to have completed the previous two Grand Tour Adventures, Lost in the Underdark and Leemooggoogoon Rises, in order to access these new Adventures.

Neutral No More

Head to Mantol-Derith to learn more about the demonic incursion into the Underdark.

• Variant: Fungal Excitation — On the way to Mantol-Derith the party is attacked by a flood of Spore Servants! These Underdark Spore Servants do not count towards quest progress, nor do they drop gold. Each time you re-encounter an area, the number of Underdark Spore Servants increases!
  Reach Area 425.

Encroaching Madness

Explore Mantol-Derith while you discover the reason behind the inter-faction war.

• Variant: Watchful Eyes — The Zhentarim are willing to help but are also warry of betrayal, so two Zhentarim spies join the formation for this adventure to keep an eye on things. You'll need to be persuasive to keep these Zhentarim trusting you, so only Champions with CHA of 14 or higher can be used.
  Reach Area 425.
