 Title: The Scepter of Ages

**Setting:** The adventure takes place in the ancient city of Erelhei, buried deep within the Earth and forgotten by time. The city is filled with traps, puzzles, and guardians protecting the Scepter of Ages, a powerful artifact said to control time itself.

**Objective:** The party must find the Scepter of Ages and bring it back to the surface.

**Encounter 1: Entrance Puzzle**
The entrance to Erelhei is guarded by a magical barrier that can only be deactivated by solving a puzzle. The puzzle consists of a 3x3 grid with 9 runes. To solve the puzzle, the party must arrange the runes in the correct order, which is: Past, Present, Future.

**Encounter 2: Trap-filled Corridor**
As the party ventures deeper into Erelhei, they encounter a long corridor filled with traps. The traps include:

* Pressure plates that trigger poison darts (DC 15 Dexterity saving throw to avoid, 10 (3d6) poison damage on a failed save, half as much damage on a successful one)
* Tripwires that trigger falling rocks (DC 15 Dexterity saving throw to avoid, 14
This one-shot is designed for a party of 8th level characters. The PCs must journey to the ruins of an ancient city to investigate a mysterious artifact. Along the way, they will face a variety of creatures, including a pack of wolves, a giant spider, and a group of bandits. If the PCs succeed, they will find the artifact and use it to gain powerful new abilities. The final battle will involve a surprise twist, and there will be cool layer actions such as dodging lasers from a robotic dragon. There are also traps and puzzles to be found throughout the ruins. The GM should describe all of these in detail to help create a smooth and enjoyable one-shot.
