'It looks like we are trapped in this area,' said Arch.

'Seems that we had been searching forever,' said Selph.

'All our equipment and compass does not work either,' said Star. 'Not even from the satellite scan. We don't even know how huge and deep this labyrinth is.'

'Don't worry, I have marked down all routes we had went through.' said Selph.

'Is there even a limit here?' asked Arch.

'Well, that's the point of labyrinth,' said Selph. 'It was built in the first place such a way to puzzle anyone who wishes to cross this threshold.'

'You are right about that,' said Arch.

For days they carefully proceed deeper into the labyrinth until they finally reach a heavy iron door guarded by two Specter demons.

‘Something valuable must be stored behind this armored door,’ said Star. ‘Maybe we should take a look.’

‘Specter aren’t easy opponent,’ said Arch. ‘I fought one before.’

‘Then leave this to me and Star,’ interrupted Selph as she stepped forward gracefully. Both of them walked through the dark corridor towards the gate.
