While playing the Torians I noticed an oddity with the Shimmering Depths faction.  As shown in the first screen snapshot below, when you hover over the name of the faction (in this case the Endless Emporium) a popup window appears that shows which leader traits will affect the bonus/penalty gained from the faction when you assign a leader to that faction.

However, as shown in the second screen snapshot below, that does not occur for the Shimmering Depths faction.  The popup just shows the current effect the faction is having.  When I assigned a leader to the Shimmering Depths faction I could see from the trait icons that appear in the upper left-hand corner of the leader's picture that the relevant traits are Resolve and Diligence.

Please have someone review the popups that appear for each faction to make sure they show which leader traits are used to determine the bonus or penalty that results from assigning a leader to the faction.
