I Got Kicked Out of the Hero's Party, So I Built a Dungeon to Fund My Retirement

Gray was the logistics master who kept the Hero's Party alive for three years. When they found a Bag of Holding and fired him before the final boss, he didn't beg. He handed them a bill and walked away. Now he owns a Dungeon Core in the only safe pass through the Southern Wastes. He's not building a death trap—he's building a business. And when his old party comes crawling back, broke and desperate, they won't find a friend. They'll find a landlord.
