In “The Last Mage” we learn that teleportation can use memory as an anchor point. It can use something as simple as a plant’s memory of where it was grown. This means that plants hold memory. We’ve recently been introduced to memory magic with the Kyrian and the Primus in the Shadowlands who use Anima as a source of their magic. Since non-sentient life can hold memory it may be that memory is linked to Anima and thereby Spirit and Decay, meaning you may be able to access memory via these raw elemental pathways.
This then could explain how Druids in WoW are able to Dreamwalk and physically teleport to the Dreamway without arcane based teleportation. Since most of the trees in the Dreamway are connected to G’hanir in some way (via the acorn used to plant Nordrassil) it means you are literally traveling a spirit/memory network of G’hanir, the Mother Tree. That in turn poses an interesting question about the origin of G’hanir & how Amirdrassil connects to the Dreamway. Since we know Elune is connected to the creation of Amirdrassil’s seed and that She offers seeds of trees in The Legend of Elun’ahir as a part of her portfolio and habits it may be an even larger network of seeds and trees connected to Elune and spans the cosmos (See Thiernax). Further proof that it may be Elune’s memories is the fact that your character casts a moon spell effect and you are bathed in moonlight as you cast Dreamwalking. As an added note we’ve also seen this type of non-arcane teleportation magic in Ardenweald with Marasmius’s fungal network which again likely uses anima, spirit, and/or decay.
Since all life, sentient and non-sentient, has memory and spirit it provides some more clarity on other things like how Malfurion is able to speak to trees (essentially he is witnessing their memories) and more context regarding the Wild God, Aessina. This connection of spirit with all things may explain why she is “the center of the web of life.” She is essentially a Wild God of Spirit connecting all living things. It is no shock then that she is found deep in the oldest and wildest of forests where the concentration of Spirit from old trees is strongest for her and wisps to manifest. It too could explain why those that are deeply devoted to a particular forest and the spirit of that forest become wisps to serve in death because their spirit is so closely tied to that one place.
This may also expand our understanding of the Ancients of Lore, War, and Arcane as well. We already know that Ancients have vast knowledge and wisdom and pass this knowledge on to Druids, but this access to Spirit and the memory of the plant life may be the source of their knowledge making them vital tutors in this interconnected web of life.
It may be that the environment that an Ancient is from or tends to informs what they will become - an Ancient in a peaceful place with many Druids may become an Ancient of Lore, an Ancient from a land that has seen continued conflict may become an Ancient of War, land that has been heavily influenced by the Arcane may become an Ancient of Arcane. We also see that the biome they are from affects them as well. We see this with the coral like Ancients in Nazjatar and the Ancients on Dreanor that reflect their biomes in how they are formed.
This web of life/spirit in nature may also be why Blight and Fel corruption are so hard to cleanse and why it affects the elements as well. Both Blight and Fel may use the spirit of the land and nature to continuously fuel itself making it a magical runaway fire that is almost impossible to control. Fel in particular seems to use Spirit like kindling. For example, the fact that warlock spells require souls or the sheer mass sacrifice required to open the Dark Portal. Nearly every zone you go to that has been touched by the Fel is either in a state of decay or completely barren. The Blasted Lands and Dreanor may be the way they are because of the sheer power required to maintain the Dark Portal’s opening and all the other portals opened that it turned on the land to fuel itself.
The corruption of Spirit poses an interesting concept as well. If Spirit is the conduit of memory then perhaps Decay acting as Spirit’s elemental counterpart is the conduit of madness and why it pairs so well with the Void. This lines up with things like the Emerald Nightmare and Shadow Flame, both have connections to the Void and both drive those corrupted by it to madness. While the Void and its infinite possibilities and whispers may be the source of madness, the element of Decay may be the channel by which it is able to make contact.
With a network of memory like this there is no need for recorded history. Just like Druids of our own history, knowledge is passed down from Teacher to Student, Shan’do to Thero’shan and on Azeroth the forest itself may be your teacher if you are able to listen.
For Roleplay of a Druid, all of this may offer your character a new reason to hold a grove, a certain forest, and the land so sacred because they hold ancient memories that can be passed down. Also maybe this might help players see the enigmatic network of knowledge your Druid might have access to.
For shamans this may help as well with visualizing how your connection to the elements may work as well! Especially if the elements are under a specific influence or corruption type.
Also in my personal opinion this all means that D&D spells like “Speak with Plants” and “Transport via Plants” are viable spells for Druids in WoW rp with all the concepts stated above as long as your character has a memory of that tree/plant and your dm’s permission of course!
