Understanding the Crusade

Understanding the Crusade is a sidequest that can be acquired in Chapter 10 of Baldur's Gate: Siege of Dragonspear.

Obtaining
Speak to Deneld in the eastern section of the Castle Dragonspear Exterior to be given this quest, which requires you to speak to multiple individuals around the camp to learn more about why the Crusade exists, what draws people to follow it, and what its goals.

Completion
The player must speak to the following NPCs scattered around the camp, and then report back to Deneld:
 * Ravoc
 * Sindret
 * Tristian
 * Zare

When reporting back to Deneld, he will ask you three questions; the correct answer (option 1) only appears if you have spoken to the right NPC. If you cannot answer all three questions correctly, he sends you away to find the remaining NPCs.

Reward
Upon answering Deneld's questions to his satisfaction, the party gains 2000 EXP and a magical ring, the Ring of the Crusade.

Note
A counterpart quest to this exists in the form of the quest Memories of Battles Past, which can be acquired at the Coalition Camp from Simonetta Twoedged.
