The Nether Dungeon.
Located in the outer ring of the Forbidden Forest, it was a massive dungeon where just the first floor alone was dedicated entirely to mining. It was so resource-rich and colossal that sixty percent of the world's current luxury resources—like gold, silver, and mana crystals — were extracted straight from there.
Though, to even enter it, one had to cross the 'Wall of Play', a barrier so incredibly tough that not only ordinary people, but even most advanced magic users couldn't scratch it. The deeper you went into the dungeon, the more massive the monsters got and the more bizarre the environments became. There were even legends that if you managed to bypass certain hidden traps at the lowest depths, you could find a map leading straight to the Abyss of Koknei.
Sera had grown up hearing these wild legends. So, knowing their second practical exam was taking place in the actual Nether Dungeon had her practically vibrating with excitement.
