While Noel and the others were discussing their escape plan, the people from the town were actually the soldiers of the kingdom and had been witnessing their entry. By utilizing Legolaz's influence, these undercover soldiers had sighted Noel and Dimitri.
Because the town was near the border, they had stationed another Spirit Grandmaster, who happened to be another Great Protector.
However, the other party didn't know anything about Noel and Dimitri as Legolaz had hidden this information. All he knew was that Noel and Dimitri had entered the town. Even with Dimitri's power, it was impossible to avoid his detection unless they were planning to loop around the city instead of entering it.
Whether it was fortunate or unfortunate, the Great Protector only put them on surveillance and told the information to Legolaz. He didn't dare to take on Dimitri or something, considering they came in peace.
