Escape From Nivix

Publisher's blurb: A 2-4 hour Ravnica adventure for Tier 2 (5th-10th level) characters. While meeting your Izzet contact in Nivix, the tower mysteriously goes into lockdown. Someone has framed you for stealing Izzet technology. Can you clear your name and navigate the hazardous magical laboratories of Nivix to safety? This adventure is meant to be played after Rumble in the Rubblebelt, but it can be run as a standalone.
