Because the parents' information is unknown, his nominal grandfather picked up the abandoned baby; It should be said that he shared Vidina and many cheap dads with the protagonists Asa and Clovis. (Because both Ronnies and Sandru said that Vitina might have two sons, but later, it was obvious that both Asa and Clovis were the sons of the Lich Woman, and it could not be inferred that Rodhart was the son of the Lich Woman just because of his birthplace and abandoned baby).
His nominal grandfather was a squire in Airy. This place is closest to Whispering Forest. This should have happened 20 years ago, when Agrell assassinated Pope Deacon. She took a baby, Asa. The time and place are the same, combining the subtle information of Ronnies and Sandro; To some extent, it can be speculated that Rodhart's life story is in line with the plot.
-This is also the way the author created Asa.
