The dice remember every sin. Cast them upon the cold stone, and pray it shows thee mercy. It seldom does.
Touch the horrors themselves to wake them. Roll a twenty upon the d20 and the wyrm shall burn. Roll a one, and the Master shall feast upon thy failure.
Add or take away dice with the marks beside each, then cast. Every number is wrung from thy browser’s own cryptographic chaos. The stone playeth no favorites.
