I don't know If my suggestion is okay.
We can have defensive structures inside the mine for protection.
MC leads the defense against Goblin hordes which try to reclaim the mine.
Then, workers are paid to build barricades and defence (Ballistas, section fortification, traps, etc).
This can allow us to expand the layer and build some mine layer conquest mechanics.
(MC gains more fame and profits)
Keeps Mercenaries alive with better armour and monks.
*This can allow MC to expand his mercenary company in secret...Have self-sustain agriculture, weapon&armour maintenance*
