 // Note for the below 'phobias' are of the xeno-phobic variety, and are less centered on pure fear as above, and more on a mix of distrust, fear, and disdainfulness.
 // As such, they are mechanically different than the fear-based phobias, in that instead of a buildup of fearful messages, it does intermittent messages specific to what holder sees.
