In regards to aether and the things that weren't touched upon in Merri's link...
Aether is the lifeblood of the entire planet of Hydaelyn. All things, living or not, are created from aether. In a sense, it can be compared to the basic building blocks of all matter in real life.Â
When a creature dies and its body decomposes, the body is returned in the form of aether to the lifestream of the planet.Â
A portion of that aether lingers, and over time, that aether that is left over condenses with the other free floating aether to form aetheryte crystals.
In the case of teleporting and how it works, basically we are using the lifestream of the aether to traverse from one aetheryte crystal to the next. We do this by attuning to the crystals in question and using the spells teleport or return. Two things happen when we use these spells.Â
Conjury makes use of the aether found in nature, most notably in the elements of earth, wind, and water - the most abundant and easily ready.
Thaumaturgy uses the caster's own innate aether from within them. Every individual has their own aether pool they draw their magic from, but it is also the lifeblood of the individual. Using it without restraint can lead to severe penalties such as death. Some people are inept at casting magic, likely because their own aether pool is limited or stunted.Â
Arcanist use tomes filled with geometric gyphs to cast their spell. The type of ink used to scribe the glyph has an effect on the spell and acts as a conductor for the aether. The glyphs themselves are there for the arcanist to see the image, place it in his mind's eye, and cast the spell. It can be said that arcanist use both  external and internal aether when casting.Â
I'll add on if I missed anything, but that's all I can think of right now. Once ARR comes back up, I can provide more information.

- The body breaks down into aether and returns to the lifestream (much like it would if you were to die)
- Your conscious soul is seperated from your body but is sent to the destination you are teleporting to. The lifestream then essentially rebuilds your body with aether.Â
Fun fact - anima is defined as the inner personality turned towards the subconcious of an individual. It is also the feminine part of a man's personality. The mother crystal, the source of all aether, uses the female's voice to represent itself and speaks to our characters subconsciously. While anima was present in 1.x, anima isn't used in ARR or touched on much.

Take some bacon and I put it in a pancake.
