Angelica's Tears

"It is said the pine cones only glow when they get wet, thus it is said that when Angelica cries, the pine cones from her tree respond to her sadness and light up the night."

Information
She is referenced in the Kickstarter stretch goal, "Seeds of Angelica's Tears" which are seeds that grow pine trees with glowing pine cones. These particular trees do not reproduce, so they will die out eventually.

You'll be able to carry around the pine cones and let them act as a lantern, but they won't stay lit indefinitely. You'll be able to harvest new pine cones from the trees based on the season.
