From the Publisher's Website:
Artifacts are great plot devices that can serve as the focal point for an adventure or even a whole campaign. Luckily, the famed hobgoblin general Azagar Bloodfist has been collecting artifacts for the better part of thirty years. Now, in Azagar’s Artifacts, the infamous hobgoblin opens up his vault and lets you have a peek inside. Each installment of Azagar’s Artifacts features a new, fully detailed artifact that can easily be integrated into nearly any 4E campaign. Each artifact comes with adventure hooks, lore, and a new standard magical item on which the artifact is based. Plus, Azagar himself relates the tale of how each artifact came into his possession in his own inimitable style.
