Your visit to Ptolus was to be simple and short: fetch the Rings of Shidaar from the old magister Kelreth. But when the sage turns up dead and the rings go missing, the trail of clues leads you on a hunt through the backstreets and boroughs of the City by the Spire. This crossover event combines Monte Cookâs Arcana Evolved with a showcase introduction to the city of Ptolus. Three teams will advance to round two, hosted by the Council of Magisters.
