I've been mulling thoughts of this over lately too...same along the thoughts of the home world may be gone (destroyed by a supernova or something but we can blame Cosmos for that) but....then I wondered if the palace being from the home planet holds the "spirit" or soul of that world and allows for the spirits of the elves to travel between wherever the others pods that left the home world went? And maybe that's why it takes time for the spirits to be "woken" up or communicated with by the living? It's been suggested in FQ that there is MORE to be learned in death? I don't have the comic in front of me but by Krim? Where does the lodestone play into that thought line? I was thinking it was pointing to another pod.
