All the lore I have, check my posts and replies (bc maybe I am missing some pieces here):

magic system based on the idea that Silver gives magical powers when consumed with certain rituals... I'll also add a few weird big birds, some sea worms and other weird animals and plants... And some gods so humans have something to worship.

Silver can give you temporary regeneration if consumed (along with strength, durability, climate perception, night vision and fire inmunity, for only 24 hours, then they are gone and you need to consume more to get them again)... The Purple Plague is not silver, its your body reacting bc it is oversaturated with pieces of silver inside its blood and other organs, this sickness is a mix between argyria and leprosy... so you will need regeneration to at least live some more years... it is builded around the idea of "magic has a cost" and that is your life... the Purple Plague also makes you steryle.

I'll add a new comment to add all the other lore, it doesent fit here

Also, some humans are born with silver in their bones and blood, so they are in a symbiosis with it.
They are called Argenytes (they are the result of a healthy Silvoracle/mage having a child with a normal human or another healthy Silvoracle), the Argenytes have pale skin (VERY pale), their hair takes longer to grow, some parts of their bones are silver like colour, they have all the powers of the Silvoracles in a permanent form (both the temporary ones and the permanent ones, those permanent ones are aquired by a Silvoracle once he consumes silver, they last forever, they are: longevity, superhuman reflexes, augmented vision and premonitions... the premonitions are very rare, they appear once or twice in a year)... The Argenytes do not need to consume more silver, bc their bodies are in symbiosis with it, the are inmune to the Purple Plague... when an Argenyte is born it is common for it to be hunted down/killed or kidnapped by a paranoid or jelous Silvoracle.
