Key Areas to Explore
# 1. **The Forgotten Tunnels**

These eerie corridors are littered with debris and overgrown with moss, giving the place a decayed, forsaken feel. As you venture deeper, you’ll start to encounter hostile creatures like Giant Rats, Spiderlings, and, more dangerous still, Undead Minions.
