I've heard there's at least one robot here in Luceti. Maybe someone should ask them if they've been able to go through these 'tunnels'? Unless you're right, and only those literally brought here can leave it.

Maybe all of their power resides here, on this specific section of land—and outside the barrier, they're powerless. That's why power-caps are lifted when we leave, maybe...?
