We're going to shut the mouth of the Keeper of the Faith, aka Zilyana.
Zilyana can be found in the south-eastern corner of the GWD.
70 agility is required to get into the encampment and you need a kc of 40 Saradomin followers to enter the boss room, (beware of Saradomin priests because they are poisonous).
The lady uses both melee and magic attacks and she's very fast. The magic attacks hit everybody in the room.
Magic and melee are the preferred combat styles to kill Zilyana. I prefer melee, but a magic setup offers better magic defence. If you choose magic, avoid using blood spells because they make her a tad angry.
Zilly also has 3 bodyguards: growler, bree and starlight (don't laugh!).
