In the MOTUC narrative, it seems like the vast majority of the Horde empire is in the Eternia dimension. After Hordak was banished to Despondos, he took over Etheria. In the 5,000 years since he was banished, Horde Prime grew the empire throughout the Eternia dimension, but has kept a distance from Eternia itself. Is Etheria the only planet in Despondos that the Horde holds? This seems like a reversal of the POP narrative. Please let me know if I've got this right or if I'm missing something here... also, if this is the case, how the heck does Hordak interact with Horde Prime as in the POP cartoon?
