Island Fortress?

"Mr. De Guzman, I have another matter that I want to discuss with you." Arlan muttered in a serious tone.

Rex retracted his smile when he saw Arlan's expression. "What is it? You can tell me anything." 

"Do you know about the islands east of Catanduanes?" Arlan asked.

Rex furrowed his eyebrows and shook his head. 

Arlan grabbed a folded map of Maharlika from his pocket and placed it on the table. He then pointed to a location east of Catanduanes. There were small islands in the location that he pointed out. "This group of islands is called the Shark Reef Island. It is an obscure sanctuary island for sharks and because of past shark attacks, the islands are off-limits to the public. I bought the entire sanctuary from the government at a steep price." 

Hearing this, Rex and Renz grinned.
