What was the ultimate fate of Dr. Throckmartin and Edith after their encounter with the Dweller?

After their initial encounter with the Dweller, Edith was drawn into the Moon Pool, becoming one of the 'dead-alive' slaves of the Shining One^[1]. Dr. Throckmartin was later taken by the Dweller, clothed in 'a robe of living opalescence'^[1], and also became one of the 'soulless, mindless dead-alive'^[1].

Ultimately, when the Silent Ones destroyed the Dweller, its enslaved hordes, including Throckmartin and Edith, were freed from their 'dreadful slavery' and became 'blessed dead'^[1]. They were found 'locked tight in each other's arms, pallid face to face'^[1], and were buried together^[1].
