Common sense and the rule of cool clash over the role of the bow in the hypertech setting of the Cosmic Era
The bow is a highly intelligent weapon, with memories and plans. The wielder of the bow is a brainless zombie, who is still perfectly capable of wielding the weapon. Together, they're an NPC.
An unstrung and useless piece of cold wood, unless you happen to be dead.
Suddenly an east wind blew, and far above the clouds rolled and folded. Where there were once whisps of white there was now a long cloud formed in the shape of a recurved bow. Malakh bowed her head in humility. "That which you have asked is granted you, O Warrior."
...Vaakri reached and stretched, grasping at the sky. At first he seized nothing, but his heart was filled with the Empyrean Emir's winds and light, and finally he grasped the bow from the far sky and drew it to the earth.
- The legend of Vaakri
An ancient relic from a bird worshiping time.
"Tired of lugging about heavy quivers full of arrows?"
"...and thus it was said that Adaleer the Blest could reflect the true nature of any soul. Now some of his followers believed that his ranger gear, as much a part of him as his faith, was also so blest."

When you sleep, your soul briefly returns to the place where it was created/goes to when it dies, and seeks nourishment. Everybody's soul is created with a little link (or you could say a greater entity calls it back) to that place so that it can return easily, but upon death, the soul returns via that and annihilates the link as if returns.
Also, as an added thingy, you could say the entity supplying the link, or residue of the links themselves, (whichever) is the source of all arcane power.
