As it turns out, Yggdrasil, the central sacred tree that holds all of the multiverse, has been present in the MCU way before Loki hit Disney Plus.
In the Loki season 2 finale, Loki becomes a living embodiment of Yggdrasil. In Norse mythology, the tree holds all Nine Realms together, controlling all life and death. In the MCU, this is redefined to hold all of the multiverse, with Loki now at its center – making him the literal God of Time.
