Saving Gielinor/Zamorak/op19

You take the Dark Bow, but can't find any arrows. You suddenly fall through a trap door into a storage room that stretches to the sewers.

"So this is where they keep it all..." you mutter. 20 minutes later, you find a few arrows and start to climb to sunlight. BOOM! Something crashes over the ladder. You fall and are trapped in the storage room.

Try again?
