The plant monster seems to lurch slightly towards Sir Jimena, before it collapses seeming to fall apart, now an unanimated pile of plant matter almost 10 feet tall.

Omen races forward to check on Sir Glint.

Under the pile of now-dead plant matter, Sir Glint is very dead. The earth genasi's stone-like skin is torn from the foot-long teeth like thorns that were rotating inside the tendriculos. 

Jimena kneels beside the lifeless body of Sir Glint and attempts to examine his wound to determine the exact cause of his death. A gloomy expression now highlights her perfectly sculpted face as a display of internal turmoil and despair.

• Wisdom (Medicine): 21

He's clearly been crushed to death.

Omen looks down and shakes his head. 
"it was too late to save him." he says a bit defeated. "Jimena, are you injured?" he asks the fellow surviving knight.

Jimena covers her face with the palm of her hands like a soldier defeated in the battlefield after a fruitless fight. When she hears the voice of Sir Omen, she removes her hands and stares at him with an eerily neutral expression:

"I'm barely alive after suffering from repeated physical assault. But, I think that a short rest might be beneficial for me. Besides, we need to arrange a proper burial for Sir Glint. He deserves the respect of a knight, and we must ensure that."

"I do not think Sir Glint would give the same to us but we can return him to the Light the best we can." Omen says. 
Omen will do his best to move the body of the fallen knight out of the muck of the creature that devoured him. Omen helps Jimena stand and lets her settle down to rest for a bit while he works.

Omen does his best to clean the dead knights body and preps it for the pyre.
"i fear that in this place this good knight may return as something dark." Omen says as he works. 
After that is done Omen will look through the remains of the dead creature, looking for anything that might identify it or give it a clue ab out this place.
Investigation: 10

(Forgive the formatting, I'll fix it later, but I'm on my phone now)

Of note, Sir Glint carries a signet ring with the House Deneith chimera, a Pearl of Power, and a Bag of Holding containing the following:

Hesitantly Omen will place the magical items+ Alchemist Fire, Diamond, Sledge Hammer & crowbar in a small pile next to the fallen knight. 
Omen looks to the items then to Jimena.
"I believe these were given to Sir Glint by The Council for us to complete this quest, along with a few of the other items he was carrying. Whether we go forward or decide to return we should use these things for our supplies."
Omen pauses for a brief moment then continues.
"This quest was our last chance to gain absolution and return to the Grace of the Flame. Return in failure, we were told, meant dishonor and disgrace. That being said, I for one can not turn away from this task set upon us to find the artifact and return it to the light.I too want to find out what happened, especially since I was with those knights who traveled with the artifact in the first place. There are gapes in my memory that need filled." he says to Jimena. "As the junior knight I will follow your decision so I ask, what do you decide in this matter?"

Jimena eagerly listens to the assertion of Sir Omen, she will sometimes nod in agreement but other times she will stare at the face of the charismatic fellow knight. She appreciates the association of the knight as well as his presence, but there's no word to express such kind of valiant fellowship. She suffers from indecision on the matter of advancing farther for a noble cause and embracing the unavoidable destiny of death.

"Sir Omen! I've taken the vow to serve the Silver Flame and offer my last life essence to the promotion of greatest deed. You might be young but you're no less honorable than this knight of ancient origin. Let us be allied and pursue the common aim. We will not let the church down, and we're going pass the legacy of Sir Glint to the other knights."

"We need to follow the ancient teachings regarding the art of war and survival, and I can provide you with necessary guidance. But you must know that all my decisions will not be effective till we find ourselves strategically united."

As you stand around Sir Glint's body, you can hear strange sounds coming from the mist, something like whispering voices and painful moans. Your sight is still restricted by the mist and it distorts sound. You can't tell if something is just a few dozen feet away, or if it's a mile away.

Make a perception check.

"Blast it!" Omen exclaims in a hushed tone.
Perception: 6

Jimena: Perception 18

Sir Omen cannot seem to get a hold on where or what the sounds might be.

But Sir Jimena can hear something rustling moving towards them. At present, it's still a good ways off, and it's moving slowly, whatever it is, but if they don't move whatever is coming will reach them in a few minutes.

"Sir Omen, do you hear the rustling noise of something? It's coming towards us"- Jimena warns the fellow knight with a hushed tone. She suddenly assumes a defensive position that's the foremost requirement for survival. As a result, she will attempt to find a place where she can take shelter and the lifeless tendriculos draws her attention. She's trying to hide inside the thick growth of foliage.

Dexterity: Stealth 14

Omen reacts by notching another arrow.

"I heard it but can not place the distance." he responds. 
Omen will follow Jimena and try to hide.
Stealth: 4

Are you planning to hide and wait until it comes to you?

OCC: Not sure its the best plan so.

Omen whispers. "Let's try to circumvent what ever is coming." and tries to move through the brush, away from what ever is coming. 

(Yeah, the initial plan was to find out the true nature of the source of noise through observation. Anyway...)

"We can try to avoid a direct encounter, Sir Omen! But, I don't think we will be successful. I am fatally wounded and.."- Jimena pauses momentarily since she fails to conjure up the words to explain her current condition and the irony of the situation. She will certainly become more exhausted if she doesn't take a rest. Ultimately, the action will slow down the advancement of the fellow knight.
