Castro

Castro and his associate Felix are treasure hunters in who, along with their friends Mourdin and Thadious, were searching the dungeon Despise for the legendary Kiran Shield, with the Kiran Stones as the key. However, their quest quickly turned to disaster.

Description
On his search for the yellow Kiran Stone, Castro and Felix were caught by the enthralled Iolo, who put them into a prison cell near the entrance of the dungeon. After not having eaten for a week, the Avatar found them, bickering about their predicament.

Once freed, they told the Avatar the story of Kiran, and how they'd come into the dungeon after they had been thrown out of Britain thanks to mayor Aidon's policies. They revealed the location of the yellow stone, and that their two friends had ventured deeper into the dungeon.
