It is a small, crystalline orb roughly the size of a softball, pale white, and reflective. Inspecting the surface reveals minuscule fractals outlined along the outside of it. It is light to hold and cold to the touch, though not hollow. Holding onto it with both hands and focusing on it seems to bring about a small, faint song. No more than a deep, alien-like hum.
An item like this previously belonged to one of the arch-magi of Imea as a magical focus. The one carried by the party was found beneath a mine outside of Barren Sands after cleansing a layline of its corruption. It can provide brief magical effects such as inherent racial abilities and cantrips. It has a dangerous effect when handled by one of the Blessed, catalyzing with their gift, and relinquishing their hold on their powers.
Underneath the mountain of the world titan's heart, Bhal Todur, it revealed the truth of the world, that it was a crystalline drop of titan's blood, a creature who's death fueled magic across the world. It exploded over the party granting them further access over magic, and briefly opening a window into the past. Shards of it are now embedded into each member of the party, granting them streaks of starlight in their skin.
