Much Visited Planets

The first Nicholas van Rijn novel, The Man Who Counts, is set on Diomedes and we see more of Diomedes in the Dominic Flandry novel, A Knight Of Ghosts And Shadows. 

The van Rijn story, "Territory," features Joyce Davisson from Esperance and we see Eve Davisson on Esperance in the Ythrian novel, The People Of The Wind.

Stories featuring Aycharaych mention his home planet, Chereion, and we finally see Flandry on Chereion in A Knight Of Ghosts And Shadows.

Merseians, as well as Aycharaych, were introduced in "Honorable Enemies." We see David Falkayn on Merseia in "Day of Burning," Flandry with Tachwyr and others there in Ensign Flandry and Tachwyr there in The Game Of Empire.

Sandra Tamarin and David Falkayn are introduced as from Hermes. Then we see Hermes in Mirkheim and A Stone In Heaven. 

Several solid settings for multiple recurring characters.
