Gertrude will look at the orb, the cockroach and the sarcophagus to figure out if there are any buttons to press or any dangers to be expected. Investigation 17 

If nothing comes to mind, she'll put her full body weight into opening that sarcophagus.

Gertrude will look at the orb, the cockroach and the sarcophagus to figure out if there are any buttons to press or any dangers to be expected. Investigation 17 

If nothing comes to mind, she'll put her full body weight into opening that sarcophagus. 

 No button, lever or contraption is present anywhere near the sarcophagus. It seems the lid must bu pushed away (Athletics check). No trap seems to be placed here, either.

OOC Everyone must declare where he or she is now.

Kurma would have been close to the entrance and asked Inete to come with him. (Trying to keep 2 healers in a safe place)

Brunella stands near the side of the sarcophagus, flaming sword at the ready.

Isabella will have her hex blade and shield ready next to Irommek. 

Athletics check: 16

Dragonbait makes a sign to Artus to stay behind in the throne room, while he unsheaths the magnificent longsword and prepares for the worst.

Gertrude pushes away the lid like it was made of paper. And from inside the sarcophagus...

... a very well preserved corpse of a woman. Aside from the tattered remains of a black gown, decay hasn't touched the body. She wears also a hornet mask made of painted gold. In her left hand, she holds a sceptre with an adamantine head.

Kurma detects that the necromancy aura is around the corpse itself of the Queen, while transmutation reveals itself coming from the sceptre.

OOC Just a reminder: when Dragonbait holds the sword, he and allies within 10 feet have advantage on saving throws.

Brunella, curious, looks at the corpse. How can the body be so well preserved? She has never seen such witchcraft. The albino dwarves of her home were at peace with nature, with its natural cycle of birth, life, and death. This corpse breaks the cycle, and is anathema to nature. 

"Could this be the old queen?". Kurma investigates without touching the body and, thinking out loud, adds "I think I might be able to communicate with her."

OOC: I think I should be able to cast Speak with dead

“If you want, I suggest you do it quickly.”

« Very well ». Kurma places one hand on his holy symbol - his necklace representing the insignia of Oghma - and the other one ten centimetres over the mummified bod. Closing his eyes, he reaches for his magical force and casts Speak with dead

"Napaka, Queen of Omu, we need your help. Can you hear me ?"

Being a little too short to see too far into the depths of the sarcophagus, Irommek stands up on his tip toes after a moment of silence.  Tapping Gertrude on the back he whispers, "Is she stirring yet?"

"Napaka, Queen of Omu, we need your help. Can you hear me ?"

 Without moving nothing but her lips, the long-dead and last Queen of Omu answers: "Yes, weird one. I can hear you."

Kurma is trembling from excitement, he is talking with the Queen of Omu.
“We are deep within a Tomb created by the Evil wizard Acerak looking for a Soulmonger - something or someone that is not allowing souls to come back to the world. People are dying, condemned to the Oblivion. How can we reach this Soulmonger to destroy it?”

 Napaka: "I know nothing of the Soulmonger. But the lich Acererak had plans for six levels in this Tomb. However, it died before its completion."

"I'm afraid that this Lich might be back to your Kingdom and we might have to face it. Does it have any weaknesses if we are to fight against it ?"

Gertrude just shushes Irommek, staring at the dead talking corpse in wonder.

 "None that I know of."

Kurma takes a few minutes to think about the most important question that he could ask.
"My Queen, we could use all help we can get on our quest. We already lost one of our companion. Could you help us by giving us a blessing, magical items or guidance ?"

 "The sceptre I am holding is intended to overcome a challenge in this Tomb. Beware, though, you are supposed to swap it with the similar on the throne next room."
