Shadow Dragon's Horn

Within the world of Frieren, the shadow dragon's horn is treated as a scarce magical reagent, sought for the casting of summons. The fading away of the creatures that bear it has pushed these fragments into the realm of rare collectibles, seldom stocked anymore by the supply shops that once carried them. One example reached the hero's group as battlefield spoils, while another came into Frieren's hands generations later.

Unlike the remains of solar dragons and other such beasts, which crumble into drifting mana once their owner dies, this horn endures intact even after the creature is slain. A grim energy clings to the object, an aura that others brand as wicked, though Frieren cannot say for certain whether the emanation carries any real danger. Among mages its chief worth lies in serving as material for conjuration spells.

The hero's party recovered one such horn while clearing the Demon King's castle, and Frieren held onto it with summoning in mind. Roughly two to three decades ahead of Himmel's death, the relic slipped out of ordinary supply, leaving shops unable to stock it. Much later the city of Weise briefly turned into the so-called Golden Land, its stores filling with wares fashionable half a century earlier, and Frieren seized the chance to buy a second horn there, remarking that she never expected to own anything so precious again.
