Which of the old gods is female again?
It's funny that Urthemiel was male.... or so I thought.
Razikale, Dragon of Mystery, is the female one. The Circle in Minrathous was an old temple dedicated to her. Heck, even the Circle in Ferelden was tied to her. It was built for magical research because Tevinters thought that lake Calenhad was blessed by Razikale. The Inquisitor can also visit an abandoned Razikale temple in Jaws of Hakkon.
Urthemiel was male. Interestingly, the Canticle of Silence (canon in Tevinter) suggests his high priest before the Blight was the Architect. It also offers insight into their different characters: the Conductor (Corypheus) was tempted by promises of godhood and eternal glory in the eyes of all mortals. The Architect at first was dubious, thinking it a plan to elevate Dumat and his followers, but then he was convinced by Uthemiel too with promises of godhood, but also of beutiful designs and the chance to build a paradise on earth.
Other high priests were the Watchman of Night (Lusacan's), the Forgewright of Fire (Toth's), the Appraiser of Slavery (Andoral's), the Augur of Mystery (Razikale's) and the Madman of Chaos (Zazikel's). Who bets that in the future we may meet more talking darkspawn mages with the names of Watchman, Augur, Madman, etc.?
