Abel brought a promise with him as he left the Goff Family. The Titian Temple would always be open to Abel's blood-related kin. For now, the only blood-related family Abel had was the Bennett Family. As for the Harry family in Harvest City, Abel needed to have his own children first.
As Abel turned to his magic tower, he already knew what to do with Babala.
What could be more important to him than Harry castle? The Lord of Marshall had sacrificed everything for the castle, and Abel was becoming worried as his enemies got more powerful.
If one day his enemy decided to attack Harry castle when he was not around, Tower spirit Flora might not be able to unleash its full power.
Everyone living in that castle was basically normal citizens. Even The Lord of Marshall was a normal person, he could not live in a mana environment, so there were many wizard defense Abel could not set up.
