Richelieu serves under the Royal Mother. He presents to her a source describing the location of the Blue Eye of Gaia in The French Conniption, which leads to her forming an alliance with the Spectral Space Pirates (Sheer had been listening in) to find it. Richelieu is sent alongside each of the Space Pirates in turn to each subsequent suspected location for the Blue Eye of Gaia: an old orphanage in The French Conniption, the Chateau du Duke Dumas in The Wee Musketeers, both of which were dead ends, and finally Vasasi Castle in All For One and The Haunted Hunt.
