Ask "Is your chair big enough"?
I brought!? That's one way of putting it!
Why would you want a female, after all? You're pathetic.
Let him give us his best shot.- How's your chair? Is it big enough? - You shouted to the ghost.
- Oh no ... - Kisat rolled her eyes - You're starting this waffle again? Last time was enough for me.
- Hold on. I already met him and I'm still alive as you can see, - here you have raised your voice, - And now he's a wretch!
Councilor indifferently waved her hand and stepped aside. The ghost startled on his "throne":
- Wretch? Though you deprived me of the old power, I can still destroy you all. I subdued several forgotten beasts from the lower levels of the caves to my will. You're dwarves, you know what I mean. You brought miners, not soldiers. You stand no chance.
- You're lying. You've got nothing but a bunch of kobolds.
- Only YOU are lying here! - He jumped from his throne. - All I wanted was a WOMAN! ALIVE WOMAN!
- Why do you want a woman, huh? You can have fun with kobolds.
- They are filthy animals! Suitable only for menial labor.
- And this is the best you can do... I saw a huge dead woman upstairs. You couldn't do anything to her, much less to someone alive. Your "power" is not what it used to be.
- IT'S ALL BECAUSE OF YOU! - Ghost was about to burst into flames like in the past, but he really lost his powers and only covered hall with woeful cry, tried to throw a chair at you, but it just swayed and remained in place.
- By the way, this dwarf here is not for you, - you continued, - I'm taking care of her her myself, so you can kiss my soapy dick, dead pervert! But I know how you died, I read your snotty diary and saw your naked body rotten in that cave. You yourself hammered wooden dick in your ass while furiously jerking your dick, drooling on the moon, crying about lost love. Blind beast crept up from behind and broke your skull but didn't even bother eating you because you're ugly freak, an outcast of all nations and all gods, turned into blood-sucking heartless lonely immoral monster!
Even the god of death doesn't want you. I feel sorry for you. You disgust me, but I would not wish your fate even to an enemy.
Ghost sat back in his chair and took a deep breath.
- What do you want?
- Wand.
Kisat turned sharply:
- Adamantine! We are looking for adamantine.
Ghost smiled sadly:
- Your woman is smarter than you. But, oh well. Here is the deal, dwarf. Bury my body and redeem me from this worthless existence. When it's done - wand is yours. I'll disband my beasts, kobolds ... wand will be waiting for you on this chair when I'm gone. I give you my word. Word of a disgraceful pervert.
