After the election of Adolf in 1292 as King of Germany, she resided mainly in the Reichsburg Achalm when she did not accompany her husband on his travels.

After the death of her husband in the Battle of Göllheim, Imagina had the Early Gothic "King's Cross" erected on the battlefield.

In 1309, she witnessed the transfer of her husband's remains from Rosenthal Abbey (in present-day Kerzenheim) to the Speyer Cathedral.

For her widow's seat, Imagina initially took Weilburg Castle, and later moved to Klarenthal Abbey near Wiesbaden, where their daughter Adelheid presided as abbess.

Imagina's marriage with Adolf produced at least eight children: A. Ullrich, Die Landes- und Kirchengeschichte des Herzogthums Nassau von den ältesten Zeiten bis zur Reformation in übersichtlichem Zusammenhang, 2nd Edition.
