Please read this thread first for a more complete description of the location of the plinth and dragon statue.
Most of the doors of the plinth of the dragon statue are sealed tight unable to be opened. But some of them can be pushed open with a lot of force.
One door, etched with not only the same type of undecipherable epigraph, also has a beautiful carving of what appears to be baby Pae'il. The Pae'il don't look like any that have ever been spotted on the island, but it is very clear they are Pae. They almost look like Demons.
The door opens to a dank and musty tunnel, not unlike the tunnels that led to the cavern. Following the foul odor and muddy path will lead to a large chamber full of columns and crystals. It appears almost alien. There are large, opaque amber crystals embedded in all of the columns and natural rock formations. The chamber feels very warm and humid and the odor appears to originate in this location.
Exploring this chamber would yield only results of no consequence. It's merely a filthy, humid, stinking chamber with natural rock formations and crystals. Perhaps one of the island's miners would be interested in this place.
