Aspects are certain angles of planets (objects) in a THC, as the underlying game of $CHOICE algorithm runs.
1. Between two objects in a player's Natal THC (TNHC):
In a natal THC, angles between objects determine how the player is designed, i.e., their avatar's attributes (strengths and weaknesses) in the game.
2. Between an object in a Transit THC (TTHC) and an object in the player's Natal THC (TNHC):
When projecting a transit THC to the player's Natal THC, aspects of the transiting objects to the natal objects may provoke temporary clouts that may affect the player'sfree will.
