Start with Adam Aardvark of the Anduin Valley, and work your way down from there…
Thoroncir will, if possible, visit the Front Porch, famous for being the site of the kidnapping of Thorin & Co. by goblins during the Quest of Erebor more than a century ago. If their locations have been ascertained and they are now securely in the hands of the Free Peoples, he will also visit the throne room of the late Great Goblin, and Gollum’s eternally dark lake.
The knight-errant invites Gilraen and his other compatriots to join him.
The way to Gollum’s Lake is not yet safe. The Dwarves are still working on that. The road to the Goblin King is safe and it is a huge chamber that the Dwarves are using as a central camp inside. They also have the main smithies and have rescued nearly a hundred prisoners. The Front Porch is secured and held by a strong company of Dwarves.
Gilraen will forgo this journey. She will spend her time here nursing the injured and the ill.
Corner-cutter 
If she needs his help, of course he will do that before playing tourist. He will also see if there are any folk of Gondor among the freed prisoners.
Ghân thanks Thoroncir for his idea. He would like to see any locations mentioned by Bilbo - but will naturally help Gilraen with healing first.
After the healing is complete…
Our DM has told me that The Dwarves have been down to Gollum’s Lake already, but they don’t consider the passage safe.
Would anyone like to join Sir Thoroncir in making a reconnaissance in force to the lake? Perhaps the Elves or the Dwarves would like to send along a contingent of warriors, too - any goblins or other foes killed en route would leave all the fewer for the next time anyone ventured down there.
I’m definitely up for it- Gollum’s Lake is the site of one of the greatest turning points in the history of the world, and to come this close and miss it would be a crying shame.
Oh, yes, I am so very up for it. I won’t miss a chance to go to Gollum’s Lake.
My learned friends have the right of it - I will gladly join them.
How could I possibly miss out on a chance to go and see such places.
Count me in.
There is a large force heading down in two days. The party can join in and proceed to the lake with a smaller group. Gilraen will join and provide extra healing to those operating far below the earth.
The army marching down is 200 strong of Dwarves and 20 Hobbits, 20 Elves and 50 Men and the party. The party is assigned to a group of 40 Dwarves going down to the lake mainly to access improving the route, the purity of the water, if the lake is of much use or should be closed off instead. They are leaning towards massive collasping of most of the side passages on the way down. It was ¾ of the way down this route off a twisting bunch of side passages that Brevarn was found and rescued by Taur’s group.
The party makes it down below without any trouble and Gilraen lights up part of the cavern. Some can just make out the small island in the lake that must have been Gollum’s home.
The Dwarves determine that lake is of some use and clean if cold. The fish stock appears to be fairly good.
(Does anyone do anything else?)
Is there any indication that anyone has been here (other than the Dwarves recently) in all the 140-some years since Gollum so wretchedly tore himself away to seek the Baggins and his lost Precious? Do we find the small boat he used to get back and forth to the island? Any other artifacts?
If he has the spell for it, perhaps Deor would like to fly out to the island.
Thoroncir will utter a silent prayer to Este for the repose of Smeagol’s soul. For all the evil he did, he also suffered greatly, and in losing his own life he brought down the Dark Lord (if inadvertently).
It appears a largish battle was recently fought down here. It appears many orcs lost their lives to Dwarves and their allies. It was a good size battle and has without question disturbed the cavern. There is no sign of the boat.
Fun though it would be to see the island in the centre, I think I will pass on swimming out there.
Hraedsig comes huffing and puffing up from the rear.
“Did I miss anything?”
No, I didn’t prepare Fly or Levitate today, but I did prepare Spider Climb and I’d like to use that to nip on over to the island by climbing across the ceiling, with someone (Sir Thoroncir, if he’d accept) as a guard. Use a Detect Magic and look for more artifacts both on the island and on the near shore. Gollum got lucky once- why not twice?
Thoroncir would be glad to stand guard for his friend Deor as the mage scales the stony ceiling.
How cool is this, to be looking upon Gollum’s Lake! A riddle game, anyone?
Indeed one would need a heart of stone not to pity Gollum, who outlived his natural span by five hundred years, every day of it in misery, fearful, hungry and alone, and none of it of his own devising. Even the murder of Deagol was but the Ring’s influence on one who, I suppose, was until that day largely blameless according to the measure of his kind.
ponders
I am greater than the One, I am worse than the Enemy, the rich want me, the poor have me, if you eat me you will die. What am I?
Nothing comes to mind.
