The World Expo had a very demanding requirement for entries. Before meeting Joshua, Hyrlan has applied to enter the World Expo with her arcanotech device to the Advanced Magic University three times. Yet, in all three occasions, she was denied on the premise that there were insufficient spaces.
The Crystal Palace's floor space was limited. A portion of the floor space was reserved for the various nations. The other portion was reserved for Norland's various Advanced Magic Universities and famous alchemic ateliers.
As the spaces were truly scarce, Hyrlan, an ordinary magic student, would most definitely be rejected.
Madam Schroder represented Farucci. The floor space reserved for a country would be sufficient enough for Joshua to display 'Hearthstone' in full swing.
After coming to a decision to cooperate, Joshua and Madam Schroder's afternoon tea ended in delight to both parties.
