The construction of the Red Cathedral requires the best specialists in this expansion. With Contractors we get 10 new guilds that can be combined with the originals, 6 new blueprint cards, and a new card for the solo mode.

Many of the new guilds involve the Contractors module, which among other things brings a new board containing a map that features the main cities around Russia to which we'll send our contractors so they can summon the talent of the best specialists and artisans to build the cathedral.
