Fight a lich, unfortunately.

The skeleton rises up and stares towards the party with its piercing, vacant sockets. Even you can feel the unsettling aura this creature emits. Meanwhile, the goblin is frozen in fear. You look around to see several more tiny green heads poke out form behind crates, curtains, and more. They're all trembling in their boots. There's as moment that feels like an eternity, of the skeleton simply standing there, moving its head left and right. It finally speaks, despite it only being able to shift its jaw open and closed.

"My own minions. Sealing me away," comes a deep, echoing voice. "And you thought that would keep you safe."

The coated goblin drops to his knees and grovels. "I'm so sorry, master. Please forgive us."

"Speak. Why is it you betrayed me?"

"W-Well it's just that... you're a terrible lich! We wanted to raid the land. Pillage, and get totally rich. Dine on delicious meals, and rule supreme. All you ever wanted to do were really stupid things. We ate rats and mouldy bread. Barely had any gold. What kind of overlord are you?"

For a lengthy moment, the lich ponders. "First of all, stealing panties is not silly."

He can't possibly say that with such a cool voice.

"Secondly," he continues. "This is my lair, and you will perish for your betrayal, minion!"

A terrifying dark energy starts to envelope its skeletal figure as it points a finger down towards the cowering goblin. A mass of swirling magic appears at the tip. With an intimidating stance, he whispers, "Finger of ****," and a beam blasts forth and passes straight through the tiny creature's body. It completely envelopes it, until the goblin is nothing but ashes.

The rest of the goblins sprint towards the door in fear.

The lich then turns its sight on the party. "I'll have to ask you to leave as well, or perish."

Nyllia stands between you and this powerful foe. She grips her sword, and stand with confidence against the threat. "You will perish."
