What they found under Puebleque were spiders and... a city. The buildings were golden, of all things, with glass windows, which were either cracked or reduced to scattered shards on the ground.
The guild made its way through the streets of the city, making sure they were not separated. With Ludwig and Ebony leading the charge, the only thing they had to deal with were the smaller spiders.
This city, heck, just one of its streets, could see each one of them so rich they wouldn't be able to know what to do with their riches.
But they all knew that, if they dismantled the entire city, not only would they waste a lot of time, but they would flood the markets with so much gold the entire world economy would crash.
So, after the city was cleared by the spiders and the eggs that were left behind were made into omelets, just in case, Leander made himself a platform and addressed the guild.
