Lex had to admit, besides just protection from the retribution, and curiosity about the only city in Gilded Hollow, he had another reason for wanting to find the stronghold. If he could find higher quality resources, that would be ideal. Specifically, he was searching for something unique or significantly powerful.
Lex didn't believe that a place as rich and vast as the Hollow lacked resources that were uniquely valuable even in the context of everything else they were offering. Information and leads on things like that would be easier to find in a city, not to mention that the city had gateways that accessed different areas of the Gilded Hollow.
Despite anticipating that Mithon's karma with the Fortune Lord was strong, he did not actually plan on probing, or even properly examining that. It went without saying that the Fortune Lord was most likely a Dao Lord, and Lex was not dumb enough to invite death upon himself by touching the karma of a Dao Lord.
