From publisher blurb:
SEVEN UNIQUE WEAPONS from the campaign world of Palliven but for use in any 5E setting. This sourcebook can definitely be used as a stand-alone reference, even though it is a supplemental add-on to the Arcane Artifacts & Relics sourcebook. Where that book provides a broad range of powerful artifacts, divine relics and magical items, this sourcebook focuses on seven very unique weapons.
In addition to the descriptions, abilities and current status each weapon shares one of the legends that made it famous. So whether it is the courage of the Young Corsair wielding Gallgaeon to defend the helpless or Remdar betraying his commander and taking Darkmonger, the tales around these weapons are known by most. And like any good story, the tale grows in their telling. I encourage you to add to the legends of these seven magnificent weapons as you use them in your own campaign.
