The Foundation of Magic Itself

(a.k.a How Magic Works in the World ) (Not just about how each Classes magic works)

There are many ways for a creature to be in possession or gain possession of magic, it can not be immediately granted to those who don't meet the specifics and it must come from something else.

Clerics, Paladins and Warlocks draw their power from a deity or some other worldly being that they respect and worship. They act as a tool of their benefactors will and should they disrupt this process...they could very much lose their magic.

Wizards and Artificers are known for putting years of research and practise into magic so they can draw on it themselves. They use ingredients and spell focuses (wands, staffs, crystal balls, magic books, weapons and etc) to channel and focus this power (other classes may still need pretty much the same thing but I wanted to bring it up here).

Druids are similar to that of a Cleric or Paladin, since they have been known to draw their magic from a divine (or not) being but usually Druids are known to draw power from the Nature of the world itself. I don't say just Nature due to how Druids may draw on other parts of what makes the world so natural and primal; like maybe the snow and ice or dreams or more dangerous parts like storm or fire. They gain power from the world itself (this whole thing also applies to Rangers).

Any class that can learn magic as a subclass at level 3 (Fighter, Barbarian or Rogue ), draws magic in ways similar above mentioned classes; it could be relentlessly researched, gained from the land or from a higher being. Or it could be similar to how a Sorcerer gains their magic...

Sorcerers out of any class has the most variety in where exactly their magic comes from, simple version? They draw on magic within themselves. It could be from an ancestor who was a god, fiend, dragon or demon (list goes ON), a gift given at birth or from preforming an extraordinary deed or maybe gained by accident. The ways are endless but they do draw on their own magic within.

Monks do not draw on magic but use the energy of ki that flows through their entire being and they find themselves training and honing their bodies into well-made weaponised machines of spiritual energy. Like Sorcerers they don't draw on nothing, they draw on themselves.

Bards are weird in a way that their magic is practised and researched like that of a Wizard but draw on the magic found in their music and emotions to support allies or befuddle enemies with a song or a wink...it can be that simple but nothing of the such as well.

Than we get out of classes and look at the gods, demons, devils, fey elditrich, beast, and more. While any of the previously mentioned reasons talked about are mostly where their magic would originate from there is one particular part that suggests otherwise. They could draw on the the innate raw magic that shapes the worlds yes, but the one I want to focus on...has to with how beings can gain power from those that worship them... the power of belief is a very powerful concept and is why a being of such as these are are powerful as their said to be...but to lose that worship and belief...what happens to such a higher being?? Cause after all...
