Arkeis: The Jewel of the CultExpansion

From BoardGameGeek:

Amidst the dunes shifts a mysterious silhouette. It's hard to make out its details, as large veils hide its true form to the curious eyes who gaze upon it. But as it gets closer to your camp, you soon understand that this newcomer brings one more enigma with it, one more mystery that needs be solved… and this enigma is called ‘Meema'. The Meema Expansion contains many elements, among which Meema herself occupies the central spot: she's a fully playable character joining the four colorful characters already available! In order to fit into your games, she comes with her own miniature, player board and Experience cards. But that's not all! The expansion also contains a new scenario (0.5) in which Meema will take the stage! This exclusive episode takes place before the main campaign begins and will teach you more about her and her place in the grand story of Arkeis… -description from the publisher "joining the four colorful characters already available" was written before the fifth playable character (Professor Robert Pierce) was unlocked.
