The Blue Tide is the Tide linked to reason, wisdom, enlightment, and mysticism. People attuned to this Tide seek to expand the mind and/or the spirit, and are often scientists, mysticists, philosophers, or even madmen.
The loss of knowledge is particulary grievous for people attuned to this Tide.
Behind the scenes[]
In a theoric association of the Blue Tide and Planescape: Torment, Adam Heine said that Dak'kon would be attuned with the Blue Tide.
