Ironkerker Jail is famous for many things, including a notorious reputation for being a cold and cruel place where escape is impossible. Those arrested for crimes languish here while awaiting trial or transportation to a long-term facility. Some never make it to trial and rot away in these inhospitable cells… or meet even more nefarious ends. It’s also known as a place where the warden regularly hosts gladiatorial fight nights, where prisoners compete to earn the best cells and basic amenities. Finally, it’s famously the hiding place of a small fortune of confiscated gold and magic items, although that’s probably just an urban legend... A one-shot adventure for 4-6 characters of 5th-6th level using D&D 5e Basic Rules
