Alderac Entertainment announced Canalis, a new addition to their Tempest line, for release this fall.  The game is designed by Philip DuBarry, who also designed Courtier for the Tempest series.  Play revolves around playing building and canal titles to score points and complete secret goals.  The goal is to connect buildings to worker housing and ultimately the harbors.  Cards either Build or Scheme (preparing for future turns.)
 
The games in the Tempest series (Courtier, Dominare, Mercante, and Love Letter) are each stand-alone titles that shares a story, characters, and location (see "'City-State of Tempest' Designer Game Line Expands").  The game play focuses more on character and personalities than resources and commodities.
