Kagyar keeps an eye on this particular Relic, bestowing it on those Brute-Men whom he considers deserving of the honour. Kagyar will not, under any circumstances, permit individuals of any race but the Brute-Men to hold the weapon for long, and will arrange to have it removed, or perhaps Teleport it away if necessary, as soon as possible. Just visible at the centre of the amber sphere is a perfectly-preserved acorn. As her mortal body disintegrated, the acorn became surrounded by a protective halo of Immortal Power which hardened into an amber sphere. These spells are in addition to any spells they might otherwise be able to cast, and are granted whether or not the bearer has sufficient Wisdom to cast Druidic spells.
Any class can use the Soul's powers.
The Soul was enchanted 1050 years ago by a reclusive Druid called Relyn Blackthorn. A natural Demagogue, he managed to keep humans away from his home for nearly thirty years by using the Soul to augment his own powers, before those selfsame humans burned down his forest in retaliation. The Soul was carried away to safety by a fleeing herd of Centaurs, and has resurfaced in different parts of the world several times in the intervening centuries.
