After the magic towers were built according to the hexagonal circle's design, Abel had Lady Carrie come to his other three castles. He wanted her to set up large-sized defense circles and teleportation circles for each one of them.
For Lady Carrie, it was hard for her to understand the reason behind such a request. She thought that having one large-sized circle was enough already. To her (and pretty much anyone else), having two more installed in one place was simply too much of a waste. For every large-sized defensive, one top-quality gemstone was needed to power them. That was three top-quality gemstones Abel planned on spending.
