Chapter 2: Into The Temple...

Annika pierces the mummy once again with her rapier. Another wound opens and black ooze now covers a significant portion of the linen.
Scags' hammer delivers another blow.
The mummy limps. It wants to says something to Krenmuth but it only flaps its mouth open and closed. Apparently it is too weak to speak.
Once again it swings its scepter at Krenmuth and then turns around and fixates Melianne with its gaze.
With the mummie's desperate attack, the scepter is able to smash through Krenmuth's defences and hit him straight at the side of the head
The mummy is still fighting but you can clearly see that it can't stand much more damage.

Annika's face is grim as she sees Krenmuth crumple, but she tries to stay focused on bringing this monster down in a storm of blades and bolts.12/15 hp | AC 14 | Spells 0/2 | Concentration: Hex

"Krenmuth!" Melianne gasps and raises her hand to her mouth as she watches the Wavewarden collapse onto the temple floor. She is briefly stunned into inactivity, too shocked by their seemingly unwavering not-exactly-leader being knocked out - but when she manages to shake off the initial reaction, her eyes light up with a fire of fury. She doesn't even flinch from the mummy's horrible stare, and silently makes another attack against the undead - her blade guided by desire to protect her companions.

Krenmuth couldn’t believe the mummy’s strength as the scepter knocked his shield to the side. The cleric feels overwhelming pain, then the mummy and temple vanish into darkness. He feels movement beneath him, as if he is standing on the deck of ship.

Just as the cleric falls Melianne and Annika finish off the mummy.
All of their attacks hit and the mummy collapses under the combined onslaught.
Black ooze flows out under the body of the corpse the undead being.

Astrid and Hjalmar both rush to Krenmuth. Hjalmar produces a flask from the inside of his coat and pours a liquid into Krenmuth's mouth.
Immediately he regains consciousness.
I always carry one of those around... just in case Hjalmar remarks and winks at Melianne.
As Krenmuth is able to stand up again you can investigate the pyramid if you'd like.
Astrid crosses her arms.
I don't like this. This... thing mentioned a palace and a high mage, We... will have to consider this during our excavations. I will report this to Korsak. It seems as if the ruin here is secured, is there anything you want to have a look at before we return?

Annika nods as Astrid lays out the situation, cleaning black ichor from her rapier. "Indeed - presumably we can expect this High Mage to be of similar kind and disposition to this creature. Anything you scholars can decipher to learn more about them would be helpful. I would also very much like to see if we can circumvent that barrier to examine the artefacts behind. I do not believe our business here is finished, by any stretch, but for now it seems we are secure. Well done, everyone."

"A man after my own heart!" Melianne beams at Hjalmar, letting her hand fall away from where she was reaching for her own first aid kit and kneeling near them, examining their cleric friend's injuries. "Krenmuth, how are you feeling? Perhaps we should take a small break before going back to the camp, to let your wounds properly close. Do you suppose you might have a concussion?"

She looks over at where Annika and Astrid are conversing and calls to them: "Do you think there is anything to this mummy's scepter? I propose we check if it's safe before letting the workers deal with it. Plenty a song about careless adventurers failing to identify a magical item, you know?"

I will send some workers to try to circumvent this barrier from the back Astrid assures Annika.

Melianne looks at the scepter. It's a polished piece of dark brown wood, topped with a green gem. You think that the gem is glowing a bit but this could be a mirage as well.
Krenmuth meanwhile is able to stand in his own again.

Melianne twirls the scepter in her hands, examining the odd green gem with curiosity and feeling slightly repulsed by it at the same time. She has to admit that it is of good craftsmanship, but the circumstances make her suspect that it was used for plenty of nefarious deeds. Not the weapon's fault, she supposes, and the woodwork is lovely... Was it even intended to be used as a weapon, or did the mummy simply had nothing else?

Still surrounded by darkness, Krenmuth hears a voice say, "Not today." A gust of air behind him pushes him forward.

Krenmuth awakens to the dim lights of torches. He feels a dull pain throughout his body, except for where the warm liquid still soothes his throat. He squints his eyes to fight the brightness from his war hammer. "Thank you, Hjalmar," he says, then turns to the sound of Melianne's voice. "I can walk out of here. Is the mummy destroyed? Does anyone else need help?"

Krenmuth smiles at the news of their victory. As he gathers his wits, he observes as Annika, Astrid, and Melianne study the scepter and discuss the situation. "This place hides so much evil. I want to come back here when they work on the barrier. I don't trust what's in those crates."

Melianne can't really determine what the nature of the mummie's sceptre is. It clearly emanates a sinister aura but she can't really point a finger at its nature.
Nevertheless the ruin seems to be secured. Astrid rushes off to organize some workers and you leave the pyramid as well.
