Each morning, the acolytes wake up knowing one of each of the three "auras" the others possess.

game that depends on the aura counts for the players involved. The game is won when a player gets eight auras in all three categories. However, in giving away somebody's aura count, the player betrays that person, which angers them and may make them less likely to trade aura counts with the player. Therefore, a player has to know who to trust and who to betray, hence the title: ''Trust & Betrayal''.

To use an actual example from the game, if game designer Chris Crawford appears and lectures the player, and the player responds "Go to hell, Crawford!", then he or she loses some favor among the other characters, making the game harder to win.

Development

"Siboot", the name of the first Shepherd, is a reversal of the syllables of "Bootsie", a cat which Crawford had. Bootsie had to be euthanized due to an irreparable injury to his jaw. Crawford suffered much grief while contemplating that he was unable to talk to Bootsie in order to try to comfort him before he had to be put down. One day while pondering this, Crawford had a flash of insight: his next game would be ''Talk to the Animals'', which evolved into the very different ''Trust & Betrayal''. A preliminary
