While Guthix Sleeps

[Zaruko]

Movario licked his dry, cracked lips, not taking his eyes off the ancient book in front of him. His hand, acting almost like a separate entity, scratched spidery notes onto parchment. He knew who V was, but the references to the stone intrigued him. Fragmentary thoughts were gathering, forming up together into something important – but something was missing, some key detail. With trembling fingers he turned the yellowed page.

“The stone was clearly not of this world...”

A triumphant scratch of Movario's quill tore through the parchment. That was it! After all this time his research was finally bearing fruit!

The antiquated surroundings of the temple afforded little warmth, and the only luxury was the lone, guttering candle by which he read. The chill still reached inside, but it did not register for Movario as his unyielding research ground on through the days.

I think they called this a master quest or something like that... it's the first quest that requires every other quest be completed before you can do it.
