She thinks it would be too shameful to return to the city, naked, to call for reinforcements, get more items, and clothes. In addition, the return trip, on foot, would take three days. Three days naked.
With no other option, she decides to descend the dungeon, completely naked and unarmed. Though unarmed, she could cast magic, but with only a quarter of her full power. Even if she was completely naked, she wouldn't have any problems, because no one would see her anyway.
As soon as she passes the entrance of the dungeon she begins to descend a few steps, feeling the cold stone floor on her bare feet. He also feels, with his bare skin, that the inside of the dungeon is colder and wetter than the outside. I even felt a shiver in my body. It was dark, so she creates a small sphere of light on the tip of one of her fingers. With her other hand she tries to somehow cover her naked body in shame.
When she put her hand on her crotch, she immediately feels like she's wet with some sort of vaginal discharge. Then she begins to think in embarrassment:
"It's not possible. Am I enjoying being naked? No way!"
As soon as she reaches the first floor she finds a hallway all made of stone, lit by some magical lights. She's relieved that it's well lit.
That way she undoes the ball of light and manages to have her other hand free. To better cover your nakedness while walking.
After walking for a few minutes, she finally encounters her first enemies...
