Black Knight's underground tomb, located within the boundaries of the Kingdom of Trees, was built upon the land where Treants once rooted their existence. However, following that war, the Kingdom of Trees had become a kingdom in name only, and now only a massive structure remained, constructed through the concerted effort of one hundred thousand Undead.
The city walls stretched upward, blocking out the sun and sky. It was said that no one knew just how deep they dug into the earth, a complex network of roots and tunnels.
Such a massive structure could even accommodate nearly a million people. It was like an oversized city. If it weren't for the fact that all the construction workers were level 30 Undead, who never tired and moved as nimbly as the wind, each worth more than a hundred ordinary people, it would have been impossible to build such a towering edifice in such a short period.
A few gnarled paths between the trees fell under the cast of towering shadows.
