Everlasting Frustration is a short one-shot intended for 1st level characters. In it, players are drawn into the woods by a mysterious older woman, the druid Dahlia, whose children are too busy bickering to get rid of the green dragon wyrmling that has recently invaded their forest. PCs are charged with finding the children, mediating their argument, and defeating/driving off the wyrmling. Along the way, they can explore the woods and have various random encounters.

Everlasting Frustration is straightforward and generally well laid-out. The NPCs are clear as are the objectives, and the encounters are suitably level appropriate. While the creator recommends PCs already know each other when they enter the forest, I thought this was a good adventure to help PCs/players get to know each other in a fairly low-stakes encounter. I think it's especially good for younger players as an introduction to D&D, the rules, etc.

If you'd like a short one-shot for level 1 characters, this a good option. It's easy to understand and execute, and it has a good mix of diplomacy and combat.
