it's extremely dependent on the troll!

i'd say the average troll knows folklore about the vivifier, the unknown/forgiven and caesar in the same way the average person knows about the bible but can't recite a verse. their stories, ideas and iconography are public knowledge- but you typically wouldn't think twice about them being thrown around unless you're devout in some regard. kheparia and gaiaeon are much the same way.

the aspects are known too, but more through a cultural osmosis of their true concepts being warped and passed down through corporate suggestion and sanitization. it's all hidden in plain sight!
