Hi! Thank you for your kindest words :) I hope you will enjoy the game.
About your question: the standard Paragon System flow for a scene is: the GM reveals the scene (frames the scene) and the players will play it (it's a roleplaying game, of course). Then, the GM should ask leading questions, pushing the scene to a Trial (a conflict). The conflict will lead to the next situation (next scene).
During the first phase, you are in the free game. Some GMs prefer having a short scene and moving from a scene to the next with high pacing. But you can extend this phase as you (and the other players) want.
Finding a secret door can reveal to the player different options to face the enemies, or opening a chest can add Advantage Dice to the players, for example.
I really like to work with the Paragon System framework because it's very freely in these details.
One more question. Does Wild Magic use Knowledge Domain?
To use the Wild Magic you need to spend Magic Scroll charges. The more chargers you spend, the more powerful will be the effect - BUT more dangerous can be the consequences of the Wild Magic: per each charge spent, you will roll one time on the Wild Magic Effect table.
The Knowledge Domain is used to face contents of Knowledge like, i.e., solving a puzzle or talking with an ancient God in a forgotten language.
