    • Time-travel

The Story

The farmers of the continental mountain range of Isares aren’t much used to travellers. The surrounding landscape is hostile, there’s no major trade route and no landmarks to visit nearby. Yet, for days now, armed men have been travelling through Isares’ sparse fields and have paid the locals horrendous amounts of money for some conserved foodstuffs. Most of these men wear richly decorated armour or travel with exotic weapons. They also don’t seem to speak the language of the region all that well. Even those who speak without much of an accent are unwilling to disclose their destination, but the locals are sure it must be somewhere beyond the mountain pass. However, one thing is clear: Whatever these men hope to find seems to fill them with both determination and fear.

In this 3 – 4-hour adventure, a party of three 10th to 11th level characters will stumble across the secret tournament held once every 100 years by the “Benefactors”. Will they be able to compete against the best warriors from all over the continent? What is the fabled prize and who are these Benefactors, hiding in their castle upon “The Lake’s Reflection”?

Notes for the GM / DM

  • The featured tournament of the story isn’t all that easy to win. Therefore, if the GM isn’t ok with ending a quest early or letting the story move completely off the rails might have to fudge the numbers a bit.

  • Establishing the possibility of time travel is always a pandora’s box in any campaign. If the GM is uncomfortable doing so, the story can be slightly changed, with the Benefactors gaining their elixir of life from an alternate dimension.

  • The playtime of this one-shot can be easily extended by adding some arena fights before the big race. An overview of different enemy warriors has been provided for this purpose in the appendix.
