Silas Penumbra was the Paradox Rep in Nimbus Plaza. When players first arrived in Nimbus Station, Nexus Jay sends them to speak to the four faction representatives, including Silas Penumbra, in order to receive faction badges and join Nexus Force. Silas Penumbra sent players to begin their research into the Maelstrom by collecting ten Maelstrom-infected bricks. Players will have to bring these bricks back to Silas, who will give them the Paradox Badge. Silas Penumbra was removed in the Power of the Nexus Force update. His role has since been succeeded by Wisp Lee, Nexus Jay, and Cog Blammo.
