Yeah but, technically, in the MCU Hel is on the Earth Plane, like all the Nine Realms. This is is specifically an alternate dimension.
 * Hell: I think we should wait for a few more episodes to fully understand the nature of the Spirit of Revenge before we create this article. We still don't know if he was talking about Hel like Loki did in TTDW.
