The Monastery of St. Lucia

The Monastery of St. Lucia was an altered representation of one of Aguilar de Nerha's genetic memories.

Aguilar's Journal
''Ramirez escaped with the first piece of the Staff of Eden during the chaos of the battle at Sadaba Castle, but we learned the location of the second piece. A group of Dominican monks loyal to Ramirez are holding it for him at the Monastery of St. Lucia. The Black Knight of the Inquisition, Ojeda, has been spotted on his way there. We must be prepared!''

Dialogues
Upon reaching Ojeda
 * Ojeda: Well, well; the Brotherhood arrives! I did not expect you so soon; I had thought to have the fragment and be gone before you turned up. But as you are now here, I will have the pleasure of dealing with you myself. I will enjoy this!
