From publisher blurb:
Witness Protection is a Dungeons & Dragons 5th Edition side trek for 1st level characters, designed to be completed in a single session (or less). It is setting agnostic and can be used in almost any campaign setting or environment.
This adventure could be run in a single session, or it could take at least two sessions if the players prolong their investigation of the crime.
A local mage named Auric is the victim of a brutal crime, which the party is sent to investigate. The people responsible now seek to silence the lone, defenseless witness who could identify the person responsible for Auric's death, and it's up to the party to protect the witness and make sure they reach city watch headquarters safely to be interrogated.
It would be easier if the witness wasn't such an animal...
