Under Mirt’s Folly is a 200+ location mega-dungeon from Dunromin University Press Mirt the Long Flame was a mighty wizard a hundred years ago. He fell in love, so the story goes, with a beautiful Goddess. Using all his powers he built his true-love a temple and a pleasure palace with the intention of making her his wife. On midsummer’s eve he bent all his powers to calling her down from Olympus, luring her to our world with the sweetest compliments and tempting gifts. After several hours of calling she appeared and he proposed to her, explaining the wonderful life together he had planned for them. She was not amused. The blasted remains of the temple and the derelict palace, all made from the finest white marble, are all that remains of Mirt’s crazy ambitions. The abandoned ruins are now known by all as Mirt’s Folly. Of course, the anger of a mighty Goddess leaves deep scars in the landscape. A hundred years later the hill, despite being in civilised lands, remains an abandoned place of strange magic. It is the haunt of ghosts and monsters and all who go there return changed, fearful and anxious, if they return at all. No one knows the nature of the Curse of Mirt’s Folly and few desire to find out. But Mirt was a great mage! His powerful magic items and his many books of spells and research have never been found, not to mention the vast wealth he had accumulated. All this amazing loot must still be up there, in the ruins of the palace, or perhaps below it, in the catacombs he is said to have dug there. But who is brave enough, or foolish enough, to go and look? WormThe best-selling Under Mirt’s Folly is just one product from Dunromin University Press.

Amunrahx the Intrepid is your typical red dragon, with one important difference. He draws power both from the size of his hoard and the amount of trade and commerce flowing through his domain. Amunrahx is a Tyrant—proud, egotistic, and self-centered. “The Intrepid” is a self-given title. He is powerful and dangerous, but he is no match for a party of heroes and can’t stand up to an army on his own. Amunrahx depends on minions and lieutenants to deal with obstacles and constantly seeks to acquire more forces. As his domain grows, he gains ever-greater influence over the surrounding economy, creating a vacuum of wealth and skilled talent that chokes the life out of nearby cities while Amunrahx lounges and savors his victory. Tyrants and Hellions is a Dungeon Master's aide, containing fifteen villains complete with schemes, lairs, backstories, and everything else you need to drop them into your own 5th Edition Dungeons & Dragons campaign. Within its 400 pages you'll also find the methods, both mechanical and thematic, used to create villains that spark the imaginations of your players. Amunrahx is one of these villains, and his adventure takes up 33 pages (pg 74-93). Published by 2CGaming
