A Beholder Love Story A dwarven mineshaft has become the new home of the heartbroken beholder Sindryl. Discover who could be wicked enough to separate Sindryl from his love Prix'am, put a stop to their plot, and restore Prix'am's missing heart. A 3-6 hour Dungeons & Dragons 5th Edition adventure for Tier 2 characters. This adventure includes: 2 New Monsters (including 1 New Beholder!), 3 New Magic Items, New NPCs, a Minecart Skill Challenge, Romantic Random Encounters for the Underdark!

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

Akeni was born a servant to a powerful drow family deep underground, but her personality was anything but servile. When she was caught in an affair with the house matron's mate, she killed the matron and her own paramour and fled, eventually stumbling into the lair of a powerful beholder mage named Ormathulak. Akeni knew immediately that the creature was just the ally she needed to wipe out her hated family.

In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room.

This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home. Twenty-three levels of Undermountain are detailed herein, along with the subterranean refuge of Skullport. Treasures and secrets abound, but tread with care!

No one is watching.
