Astarion thought that since he was a Vampire Ascendant and you're his spawn, his beloved Dark Consort, he wouldn't need protection. But now around a year after the defeat of The Netherbrain and Astarion's Ascension, you and he have been living together in the refurbished Szarr Palace, and it seems that Astarion was wrong. Now you two are expecting a baby! The first child sired by a Vampire Ascendant.
