The Toilet Portal: Feeding a Kingdom Across Time

Settling back into her apartment following a five-year absence, a young woman stumbles across an inexplicable phenomenon: her bathroom plumbing functions as an interdimensional conduit connecting directly to a war-torn kingdom a millennium in the past. Seeing a valiant general trapped inside a starving, surrounded stronghold, she begins dispatching modern canned groceries and medical provisions through the portal. In return, the grateful military commander sends back rare antiques and priceless relics, transforming her modest lifestyle overnight. When rising turmoil threatens both eras, the modern benefactor must step through the gateway herself.
