The Maelstrom Exchange Device can be used to exchange Maelstrom-Infected Bricks for Faction Tokens. It is located in Nimbus Plaza, and is concealed in an anvil delivered by Paradox agents. Once it arrives, Nexus Jay sends players to Forbidden Valley to obtain a Maelstrom Hammer and find out what it is. The device is located by Cog Blammo in the Plaza, and costs 12 imagination to build.
