Even though the new building was also large, this largeness was different from the other buildings present in the city. Unlike those places, the royal palace actually had just slightly larger regular sized doors. Even the smallest among the giants would not be able to pass through them.
Escora immediately told Elena that to be eligible to live in the royal castle, any giants needed to master the art of shrinking first. As this was a signature racial skill for the royal family of the giants, without having mastery over this, even a proper member of the royal family would have to live in the outer quarters.
There were several giant guards at the outside of the castle but as they could not enter the main castle, they were unable to protect the people living inside. When Elena asked Escora about it, she just smiled and said that she would understand it after entering the castle. So with that curiosity, Elena followed behind Escora.
