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.

An ancient relic from a bird worshiping time.

A plague has hit the local area.
In humans it affects only the most vulnerable, the children and the very old, and even than it's little more than a summer cold. 24 hours of sniffles and then it's gone, barely noticeable really.
To sheep however it is fatal and the whole economy of the area is in serious trouble. If this keeps up the area could well be facing famine.
Somebody (enter the PCs) must find the rare herbs needed to make a cure.
