“Yeah, it’s probably localised on us.” 
“Let’s keep moving as quick as we can.”
Mulligan joins in the singing, voice pitched slightly higher from the nerves of the situation.
All the same, as we move, we need to be keeping defense and defensive positions in mind. Likewise, we need to be watching for spots where we could be ambushed.
Riglo will, I’m sure, be looking ahead with just that in mind. Thoroncir calls out, “My Elven friends, can your keen eyesight pierce this ill-intended mist?”
The party moves along and the fog grows colder and thicker. The elves cannot see through this fog and even they feel uneasy. Renee’s voices sound much weaker and it is wavering more than usual.
Hodwain breaks out in a deep baritone to accompany Renee and pulls his lute down and strums it softly and yet it seems to surround the entire party and warm it of heart and soul.
Gil-Gandel then adds his elven harp and a middle harmony. Renee’s light glows brighter and the fog starts growing thinner.
(The young Hobbits may add their voices if they wish, they can now follow the harmony.)
The Wildcat is actually purring against Mulligan’s head. This has the effect of relieving the tension of Mulligan altogether.
I most certainly will continue to join in the melody, never let it be said that Hobbits are not fair of voice.
Deor will join in, keeping his voice low to avoid revealing the fact that his ear for music is not the strongest.
If it won’t slow the party down, Ghân will cast Detect Magic (hoping to learn something about the mist and perhaps detect incoming Vampires…).
He will also join in the singing.
Thoroncir will add his bass voice to the party’s spirit-lifting harmony, although he is usually one to appreciate music more than make it.
Elfstan joins along with the song and keeps searching the fog for signs of danger.
If possible, Ghân will try to reassure the animals before any combat starts.
(N.B. When there is time, he will try to ‘match up’ suitable animals within the party - he himself still has 5HD of Animal Friendship available)
Ghân’s Detect Magic shoes the fog is magic and some dark form of conjuring.
The party continues along and escape the fog altogether. Another hour goes by leaving time for specific small actions.
The party’s hope are raise, but most are growing weary. Especially the Hobbits, Renee and Deor. Even Thoroncir is feeling this march, he is use to horse or ship.
What time is it now? Can we find a small hill or other defensible place to rest?
Is the weather holding? Is it still sunny?
Do we have any food or drink (like the goodberries) that would help with weariness?
A place to stop, rest, and defend ourselves would be a good idea.
Otherwise we could wind up defending ourselves from 40+ Orcs chasing us, not to mention something altogether larger.
Goodberries are either a 1hp cure or a full meal.
Ghân has plenty if anyone is peckish!
Hodwain says, “Give me a fire and 30 minutes and I will have a meal that should revitalize the weakest of you.”
Riglo comments, “The weather is turning, but I doubt it will be more than a light rain. I recall a small hill less than a mile away. Give me a good 10 minutes jog and we will take a long break.”
Elfstan nods his agreement, saving his breath (for a change).
Thoroncir is heartened by the thought of a respite. He is all for pressing on until we find a good place for one.
You just said the magic words.
