A recurring motif across Caleb's arc. MC presents Caleb with an apple-themed dog tag necklace before he leaves for Skyhaven's Aerospace Academy. He carries it with him through his Academy years, connecting it to the same emotional shape as the Pathless Realm lucky-charm beat (the star-patterned envelope). After the Bloomshore explosion and his presumed death, MC finds the necklace in the rubble. Per the Fandom About page: 'I gave him the same apple necklace twice.' The necklace recurs as a tangible token of their bond across the break created by his 'death.'
