saving throw for Rhok:   2  

Rhok stands bone still with fear spread all across his face....

Rhok's DC 10 Constitution saving throw at the end of his turn: 16

Rhok snaps out of the ghoul's influence just before the undead attack again.

Attack: 5 Damage: 8 against Rhok.
Attack: 16 Damage: 8 against Lothlién.
Attack: 4 Damage: 8 against Lia.

Only the one facing Lothlién manages to find its target, leaving a nasty bruise on his arm.

Initiative order:
18 Xarroth
17 Rhok (3, in melee with a ghoul)
12 Lothlién (18, in melee with a ghoul)
10 Three ghouls (19, -1d4 next save, Lia) (9, Lothlién)
   6 Lia (in melee with a ghoul)

Lia goes next.

Lia again casts mind sliver...
DC 14 int save, 7 damage.

Xarroth's infernal barrage continues, his spells aimed at the most damaged Ghouls.

Fire Bolt
Twinned
Bolt #1: Ranged Spell Attack: 10 Damage: 5 (fire) 
Bolt #2: Ranged Spell Attack: 17 Damage: 15 (fire)

Lia finishes the undead in front of her and not a moment later Xarroth burns to a crisp the one bothering Lothlién. Only the one that bit Rhok remains.

Initiative order:
18 Xarroth
17 Rhok (3, in melee with a ghoul)
12 Lothlién (18)
10 One ghoul
   6 Lia

Rhok goes next.

Rhok, shaking the grogginess from his mind grows under his breath and attempts to finish off the remaining ghoul with his short sword

First attack:   Attack: 19 Damage: 8   

Colossus slayer damage:  5  

Second attack:   Attack: 26 Damage: 8  

The first blow hits the undead, but the paralysis effects make the ranger a bit slower in his second swing and it missed its mark.

Initiative order:
18 Xarroth
17 Rhok (3, in melee with a ghoul)
12 Lothlién (18)
10 One ghoul (6, Rhok)
   6 Lia

Lothlién goes next.

"Die already!" Lothlién cries while casting another Chill Touch

Attack: 12 Damage: 12 + disadvantage attacking me

The last houl takes the mental damage and tries to hit Rhok, as it was closer to it already.
Attack: 9 Damage: 7.

Initiative order:
18 Xarroth
17 Rhok (3, in melee with a ghoul)
12 Lothlién (18)
10 One ghoul (16, Rhok)
   6 Lia

Lia goes next.

As it seems to be working, Lia continues with mind sliver

DC 14 int save, 7 damage.

Xarroth hopes to finish the fetid creature off with flame!

Fire Bolt

Ranged Spell Attack: 15 Damage: 16 (fire)

Int save against mind sliver: 4

The last ghoul clutches its head and falls to the floor, but before its corpse can hit a fire bolt burns it down to a crisp. The undead are not moving anymore and only your heavy breathing after the fight is heard in the throne room.

Looking around, the throne room is 60 feet long (east to west) and 20 feet wide. Four carved pillars support the ceiling in front of a limestone throne flanked by granite statues of dwarf warriors. The wall to the east has a fireplace from where most of the ghouls came crawling down after the one hiding behind the throne shrieked.

The staircase you used to enter the room is in the south east corner. There are three doors in the north wall, and another one on the west wall.

"Let's see if there is anything here..." Lia mutters, starting to search the bodies, then the room.

Investigation: 9

Looking around, the ghouls that came down the chimney are wearing plain and rotting clothes. The one that hid behind the throne was wearing fancier garb. Turning the corpse over you see that it's wearing a gold signet ring that bears the Axeholm crest: a handaxe clutched in a dwarven gauntlet.

"Well here is something..." lia says, removing the signet ring. She takes a closer look at it as she shows it to the others.

Lothlién takes a look: "So... we just killed a dwarven king? I wonder what turned them into these foul undead" he says while trying to recovery information about turning into ghouls

(INT roll if needed: 17)

"King or commoner; no one can escape the cruelty of undeath, it seems..." Xarroth lights a few more sticks of incense that may take someone to an alpine forest on a clear day during winter's peak, while saying a Bahamut prayer of passing in Draconic.

After the prayer, he pauses before speaking out of respect, "do you think we can use that key to access the contents of the chest, perhaps?"

While the dwarf hiding behind the throne was wearing fancier clothes, there was no crown on their head.

The ring looks about the right size to fit in the indentation the chest had instead of a traditional lock.

Lia smiles as she notices the ring would fit in the lock of the chest they had found. "Let us return to that chest and see what is inside of it." She suggests, holding the ring as she moves back towards that previous location.

"Agreed!" says Lothlién, curiosity transparent in his voice
