Yes, brown shot with Green light, so Thinker gets the Pseudo-Silmaril.
Who led the Rohirrim through Druadan Forest.
the wild man (Ghan-buri-Ghan)
Correct Thinker; a pretty bauble for you.
With what chain was Morgoth bound after the War of Wrath
Angainu, translated from elvish would probably mean "holy iron" or "angels iron". in Quenya the word is used also as for "chain", though this is a personal name rather than simple noun.
Maybe could also be called Ainuanga, but the last one is not attested (simply my own speculation).
Also Angainor is attested, probably suggesting that the stem is "ANGAINO-", here listed as regular plural form, translated as "holy irons" or "angels irons". These would also mean that Angainu is Dual Plural, suggesting "pair of chains" and not a single one.
Arath will correct me If I am wrong with the grammar. Is the answer correct, Grondmaster?
'Angainor' is the word used in
The Silmarillion and as that was included in Ammornil's dissertation; he gets the pretty bauble.

What did Bilbo lose as he escaped from the Misty Mountains
Hint: I wasn't his marbles, he lost those when he was a mere hobbit-chile; and it wasn't the sawdust filling his head, for the vacuum cleaner got that long ago when he was supposed to be helping his mother with the spring cleaning, and accidentally put the crevice nozzle up to his ear.

Another hint: Something about the goblins' closing backdoor.
That would be the famous brass buttons on his waistcoat (vest). I say famous because during the filming of LotR Weta Workshop made sure Ian Holm had some on his costume.
