Aster regretted his fight with Ramuja a while ago. He never thought that his pride and willfulness would lead him to be captured by mercenaries and got him into this current situation.
Aster looked around, trying to find escape, but Merry already calculated everything. She didn't want her prey to run away again this time. Yeah, Aster was now in the Bellleresse Castle, owned by Lady Merry Belleresse. He was tied to a chair with a steel chain and he was placed inside a big, plain room on the third floor, presumably a guest room.
This Belleresse Castle was just an old castle that was empty, because the last Countess of Belleresse died old, childless, without any relatives. She donated all her wealth to the charity and this castle was left deserted under the care of the empire.
