The Arcalian Chapter was a chapter on Gallifrey. Time Lords belonging to the chapter wore ceremonial robes of green.


In the pre-time travel days of the Gallifreyans, the Arcalians were the most prominent chapter, with the Gallifreyan Council being all-Arcalian. After the Prydonian solar engineer Rassilon's coup, his Chapter replaced the Arcalian Chapter as the dominant one, and so it remained as the Gallifreyans made way for the Time Lords as Rassilon continued to restructure their society from the ground up.
