Although she was heavily pregnant, Willa left Italy, too, travelling through the Alps in the winter to rejoin her husband in Germany.
[7] Berengar held Willa in high regard and designated her his consors regni (partner in rule).
[8] The contemporary chronicler Liutprand of Cremona, raised at the court at Pavia, wrote about both Berengar and Willa in negative terms.
He included several particularly vivid accounts of Willa's character in his Antapodosis, including that she supposedly committed adultery with her chaplain Dominic, "a small priest, puny in height, soot-coloured, rustic, hairy, intractable, rough, shaggy, wild, uncouth, crazy; rebellious, iniquitous, with a tail-like appendage".
When Berengar was fighting against Otto I, Holy Roman Emperor in the early 960s, Willa and her sons, Adalbert of Italy and Guy of Ivrea were frequently by his side.
