Time runs left to right. Barovia is the continuous band along the top; each domain joins as its own coloured band at the year it enters, stacking downward so the timeline widens as it runs on. The reader holds a fixed year at the gold line: scroll right to move forward, left to move back. It begins at the earliest recorded year.
Bands are coloured by domain; event markers by dating tier. A hollow marker on a faded pre-section is history from before that domain entered Ravenloft.
The panel magnifies the year at the reader line, naming everyone alive with age and place. Scroll (the wheel moves time sideways), or focus the timeline and use the left and right arrows. Click a marker to open the event; a numbered marker means several events share that year.
