Chapter 2: Rotten Halls

Zean seeing that his spell didn't work and hearing the explosion of glass-like crystal is ready to go inside the chamber.

"Why is it always skulls?"

Fire Ray from each of levitating skull's aye sockets try to hit Tinkara, but she avoids both rays not without an effort.

Zean not knowing what is happening inside the chamber and not being sure if it had something to with what he tried to do with his attempt to theme the stone scull, rushes towards it opened jaws with intention to assist Tinkara inside the chamber.

When [if? :)] he crawled through the small hole, he falls on the floor, supporting himself not to brake his nose on the ground. When he rises his head he sees the fling skull, that is apparently gathering its strength after last shoots at Tinkara. Zean crawls towards the sarcophagus to - hopefully - have some cover from skulls shots, shouts:
"Tinks, take cover! I will try to provide us with some more time!"

and then peeks around the corner at the skull and says an invocation of Banishment.

Throgins and Ixion see the flames gout out of the other skull aye as Zean crawls through
The skull disappears as he cast the spell

Throgin rushes over toward Tink.

Having dodged the nasty rays from the skull, I will fly as far upward as possible into the curved space behind the entrance skull and hover there, ready to cast a cantrip at anything that moves and appears hostile.

"That was you, Zean? Well done!" Ixion said as he waited outside the open maw. "Is it gone for good?"

Someone should remain outside if the jaw snapped shut, Ixion thought, but he also readied two force blasts should the burning skull reappear.

When Throgin climbs into the mouth the lower jaw try to close with a force so strong that it eventually break the handaxe jammed into it, but it gave Throgin enough time to safely get through and gear jaws closing behind him.
It openes again a few seconds later. Ixion and Vatoris see flame flickers within each of its eye sockets again

"Throgin?! Everybody good in there?!"

I am taking an overwatch role, ready at my high position to engage whatever appears in the room. I'll hover there and cover the others while they do things in the room.

Throgin yells back outside Yeah we are good!

Tink point to where Zean made it vanish!

Then Throgin will get in a position where he could prep an attack for it to come back.

"While it's gone, maybe we should take advantage of this time to take a look inside those holes and the sarcophagus."

I point to the spot behind the sarcophagus where the skull was last I saw it.

"Most certainly... the thing will reaper very soon, I'm now holding it off this plane, but can hold it too long... uhhh..." - one could see an expression of struggle and concentration on Zean's face and even a one or two drops of sweat on his forehead - "let's prepare to end it existence once and for all. Its time is long overdue. And let's not leave it to cause troubles in the future. The place where Tinks points... let's prepare there to make a final blow."

WIth those words Zean walks carefully towards the last place they have seen flying skull, draws his Maul from his belt and prepares for a strike.
