Kazri checks if there are other tracks, and also if the moose's tracks ends at any particular place in this area.

"Well this is certainly unexpected.   The tracks certainly lead here by I don't see the moose anywhere.   Stay here and I'll scout around the perimeter and then return. "

He pulls the hood of his cloak over his head and sets out to go around the site in a counter-clockwise direction.

(Well, I was close to the mark on the bear thing, so there's that.)

"Certainly... concerning to an extent." Rhogar commented, agreeing after a fashion. "But, as you wish, Chill. And if something comes up too dangerous to deal with, do not hesitate to get out of there." He request as well. As Chill starts to stride away, Gorrah takes it as her cue to pop out of the hood to follow, only to be grabbed by caught bodily at the waist. "Whoa, there! -You- are still on probation for last time's little heroics, little one." He reminds. But when her only response is more flailing about and the image of rude gesture being projected in his mind, the bronze sighs and temporarily dismisses her to a pocket plane for the time being.

"She used to be so lazy before. But now is the time she decides to get more adventurous?" He asked noone in particular, and sighed again soon after. 

Krom nods to Chill as he starts scouting the perimeter "Maybe the white moose is the guardian of this tomb." says the dwarf to the rest of the group "It's a beautiful place. I would like to check the crystal, but I will wait for Chill and Gorrah to finish their scouting."
The dwarf, placing an hand on his hammer and murmuring a chant of Guidance,  scans the area around the group ( Perception 19 + Guidance 2 )

From what Kazri can see there are tracks in and around the area so it is hard to discern where the tracks may have ended.

Chill works his way around the perimeter of the area.  He is gone for about a half hour before making his way back around.

He can report the following.

Six elevated, white marble statues arranged in a line depict slender, robed figures facing northward. The engraving on their faces has been worn away by the wind, but pointed ears make the statues identifiable as elves.

Embedded in the hillside south of the circular indentation is a stone door with no visible handles or hinges.

Atop the eastern berm, a granite sarcophagus rests in a half-circle defined by five crystal pillars. 

In the middle of the gazebo sits an unlit stone brazier.

Rising from the center of the circular depression is a tall, triangular, crystal gnomon—a device one typically finds in the middle of a sundial. It is thick near the base and narrows to a sharp point at the top. 

Chill does not see the moose though he does see other tracks coming and going from the north but cannot tell if the coming or going is the most recent as there are multiple sets of both.

Krom, under his own guidance, sees nothing moving.

Out of the darkness Chill returns,  his scouting job done. He removes his hood and shakes off the snow that has accumulated on his cloak. 

Describing what he has seen he gives his report. 

"Do we wait to see if something happens or move in to get a closer look?  I'm good either way.  If anything or anyone approaches they will certainly see my tracks.  I'm light on my feet but not that light and I can't walk on top of the snow."

Rekuberk raises an eye towards the strange behavior of the bear before giving a shrug and moving to follow the others towards the tomb. The half orc almost asks if it is strange for a single elven tomb to be in such a place but shrugs it off as it is not the most unexpected thing they have seen. "I say that we observe for a bit to see if someone approaches"

"I agree, let's wait for a while." replies Krom "If nobody approaches I would like to take a closer look at the sarcophagus and that stone door." continues the dwarf.

Krom, even if he is not an expert in elven history, thinks for a while trying to recall if he knows something of elven settlements in the Icewind Dale. History 14 + Guidance 1

“Agreed.” Kazri crouches down, and pets Oli while they wait.

You choose to wait for a while, just to see who or what may come and go.  It isn't long before your patience is rewarded.  You see a white moose emerge from under the hillside, stand in the moon dial, and sniff the air for a few minutes before ambling back toward Lonelywood, presumably to continue its reign of terror.

It will be about 100 feet away in about 1 minute.

Rhogar's eys go wide seeing the moose. "Hmm... most interesting, and... a might disturbing," Rhogar at least whispered with eyes narrowing in speculation as initial shock ran its course. "If we yet wish to speak with it, and perhaps uncover more about this area, now might be our only chance... Lady Kazri?" He looks to the paladin, gauging her feelings above all on the matter. Because if left to him, and knowing what it had done in the recent past...

He knew himself too well to consider any peaceful resolution coming about from a choice left to himself on the matter..

“I will try Mr. Nimbatuul.” Kazri casts again Speak with Animals. “Can you understand me? What is your purpose here?”

The moose stops in its tracks when it sees Kazri and cocks his head to one side when she speaks to him.  He replies back initially in a language you do not understand but then switches to a way she can understand by use of the spell she has cast.  Clearly the animal is no dumb moose.  You judge he may have been awakened as the plesiosaurus had been.

"I can understand you.  More hunters sent from Lonleywood to try and stop me?  The forest is to be free of loggers.  That is the purpose given to me." it replies

As the white moose appears Krom whispers to the rest of the party "It does not look friendly to me." The dwarf put his hand near the war hammer preparing himself for combat just in case. "What does it says lass? Is it an awaken beast like the plesiosaurs?" asks to Kazri.

When the moose came into sight he knew the inevitable result of the situation.   If this was one of those awakened creatures it probably wasn't going to be as nice as the other.  

He pulled the hood of his cloak over his head and moved to the side to hide and readied his crossbow.

With one hand she asks her companions to stand down, as she raises her other to demonstrate to the moose she does not want to harm it. "I believe we have another case of an awakened creature, Master Krom." Kazri says in a low voice. She takes a non-threatening step forward, and addresses the creature. "We will not harm you, as long as you do not harm us. We would like to find out why are you threatening the people of Lonelywood. Who gave you purpose? Does it happen to be a druid?"

Rhogar refrained from following Krom's reaction, if only reaching for any other weapons. But, his grip remained tight on the staff/walking stick already in hand while observing the situation. Though prefering to remain out of sight and focus, had Kazri's gesturing alerted the beast to the rest of the party's presence (minus Chill), the Bronze is content to avoid attracting in further attention by trying to rectifiy the new problem. Instead (or in either event), he stood quietly at the ready to act a moments notice.

Chill slips off quietly and unseen.  The moose was to busy paying attention to Kazri see the stealthy tabaxi move away.

 "Do not lie to me.  You are here to stop me.  I may be a moose but I am no stupid moose.  Even if you kill me Ravisin will stop you.  The loggers will be stopped."

As the moose says this he begins to move forward.

Kazri takes another step forward, and raises both hands. "I tell you the truth, and we really do not want to hurt you. We met another creature on the lake that was also awakened by Ravisin. Fortunately, we were able to come to broker an agreement that benefited both the town and the creature. We are hoping that we may do the same with you." While Kazri speaks with the moose, she uses her Divine Sense to see if she is actually speaking with an undead creature.

Krom frowns as he hears Kazri saying that the moose is another pawn of Ravisin. The dwarf puts away his hand away from the hammer in sign of peace, but mentally prepares himself to spring into action if necessary.
