Thanks, Aravanna
And Silvan_Haven, Will lives much of the time in a hollow under the bush. At other times, he stays with some of my other characters at the Rescue Center a little ways out of town.
The bush has sort of the following characteristics: It has multicolored hard berries which glow. It often makes a humming sound (usually a chord). It is non-sentient, i.e. it does not have a soul. It would be equivalent to the awareness of a (non-talking) dog. It grows in a sort of hibernation until a sentient being takes refuge in, under, or by it. It then wakes up, and starts glowing and humming. It forms friendships with its guests, and their friends, and if it can sense danger to them, it can form a green force field around the area. This can stand massive amounts of energy, and in doing so becomes even stronger, although, as we saw earlier in the blast which came at the rescue center, the bush can be injured by overwhelming force.
