For the LiveJournal tolkien_weekly "Potter's Wheel - Throw" challenge.
As his last arrow flies, Legolas sees Aragorn weaving along the battlements towards them – and behind him a great Uruk clambering on to the parapet. Without time to shout he whips round, snatches a black blade from the belt of Gimli’s slumped victim, hurls it –
Aragorn looks from the Uruk, sprawled with the knife between his eyes, to the Elf.
“Nice throw.”
