Custom logphrases consist of 4 different messages:
1. Story window arrival
2. Story window departure
3. Dialog window arrival
4. Dialog window departure
The dialog window can be pretty out there, but the story window needs to be something that makes sense and is possible for the character to do. Essentially, story window is completely IC, the dialog window can push the boundaries a bit. For example:
Story Window Arrival: Quilic arrives and nods politely, quietly alerting you to his presence.
Story Window Departure: Quilic offers a polite nod and leaves quietly.
Dialog Window Arrival: * Looks like Quilic is awake. Good morning, Elanthia!
Dialog Window Departure: * Quilic just nodded off.
