(You unfold the paper. It seems to be some kind of blueprint for a large complex.)

(There's an X drawn on one of the areas, and someone's writing on the other side.)

(A Dragonbound document like this would be of interest to Ortiz.)

You look quite serious, your character. Did something happen?

This? It seems to be some kind of blueprint.... Hmm...interesting....

Remarkable! You've found a complete map of Subterranea!

Only a high-ranking Dragonbound would be carrying something like this! This could be of great use to us!

1. Bring the Half-folded Paper to Ortiz.

You obtained a Half-folded Paper from a Dragonbound. Take it to Ortiz.

While dispatching the Dragonbound, you found a piece of paper with an odd blueprint on it.

Since it seemed related to the Dragonbound, you took it to the Reian tribesman Ortiz. He identified it as a map of Subterranea.
