OK, mine is Theodens speech in the battle of Pelennor because I absolutely loved it ... the last two words are Adûnaic (though Im not sure about the construction of the first one), language of the Men of Númenor, ancestors of Gondor and Arnor... well, they mean something like "swords" and "Against The Gods"... the avalôiyada-one comes from an adûnaic sentence by Tolkien, "...Ar-Pharazônun azaggara Avalôiyada...", meaning "...Ar-Pharazôn / was warring / against the Valar...", and I immediately loved the last word, its so beautiful... and as I absolutely love the Adûnaic language, my next siggy will be "îdô Nidir Nênâkham, Bârî 'n Katharâd", a neo-adûnaic construction, meaning "Now we come, the NINE, Lords of Eternal Life..." (the nazgûl 😛 ), used in the soundtrack when the Black Riders appear.
My banner is also selfexplaining... Melkor, the Dark Lord of Middle-earth and true Lord over the World... 😍 he's simply the coolest.
The sentence refers to his banning into the Outer Void Kúma
Yey I got it from Sauron 🙂
