Wow. This explains everything that has ever bothered me about Grandpa. Especially the fact that he continues to appear after the four candle evaluation. HaHaHa, gramps, your soul will never really be at peace!Grandpa was a magician. He didn't want to die so he cast a spell to make himself immortal. It backfired and caused his spirit to split from his body but remain stuck in Stardew Valley and his body immediately died.
