Ragged Hollow Nightmare is a low level (1st to 4th level) starter adventure from Joseph Robert Lewis that comes in both an OSR and 5E version, separate downloads for the same purchase price of $5. Despite the separate PDF, it's pretty clear that it was originally written for 5e and converted to a generic OSR format. It's also written for his campaign setting, under the "Dungeon Age" brand that seems drawn from the real world more than the typical D&D fantasy world, including an allusion to Christina Rosetti's deservedly famous poem, Goblin Market.
The basic premise of the module is that an evil force has been accidentally unleashed inside the local Temple (the local clerics apparently not using the augury spell) which has caused a force field, or veil to surround the temple keeping the evil in. Unfortunately it also has trapped much of the townsfolk who were at a bingo game or something. The PCs want to get inside the temple to rescue the townsfolk, but they need to find a way to climb up and over the forcefield/veil (which is about 60 feet high).
