Okay, I don't have all the details/requirements, but i've got the framework and story.

This is ment to be a difficult quest, both in itself and also the requirements. Think of it as the evil version of a slightly easier WHile Guthix Sleeps.

[No Name Yet]

Quest Requirements:
Monkey Madness
Legend's Quest
Desert Treasure
Seven subquests of RFD, all finished reccomended

Levels:
65 Hitpoints
75 Cooking
Combat level high enough to defeat several mid-high level enemies with almost no armour and a rune weapon.

Items required:
Cleaver/Kitchen Knife from Culimancer's chest.
Several cooked sharks

Walkthough:
1. Go to the Bandit Camp. Speak with Eblis (The guy from Desert Treasure) about how you can help avenge Zaros. He will tell you that you must attack in some way a Sara/Zamorak religious establishment, reccomending Eterna because of its significance. Ask him how you can attack an island that dosen't allow weapons and he will ask if you have strong connections to the Gnomes.
2. As you have finished Monkey Madness, you are a member of the 10th Squadron and therefore are well trusted. You and him hatch a plan together.
3. Go to the Grand Tree. Find Daero and have him take you to the gnome glider hangar. There, talk to the hangar person (Whoever they are), and ask him to teach you to fly a gnome glider. He happily does.
4. When he's done teaching you, he talks about the newest gnome glider design, soon to take off from Al-Kirad. It's designed to be like today's airplanes, ex. carries several passangers and cargo. He brags about designing it himself.
5. Return to Eblis. You and him will have a conversation, and he extends his plan. He gives you a suitcase and tells you he wil sign you up to be on the landmark first flight of the gnome glider.
6. Buy several pieces of clothing, Fremmenik, gnome, capes, tops, aprons, whatever. Just around 15 pieces. Then, take swamp tar to the still near Rimmington and convert it all to lamp oil. Fill the suitcase with these things.
7. Fill up your inventory with your cleaver/kitchen knife, your suitcase, and several pieces of cooked shark. Wear only an amulet, ring and Legend's Cape and go to Al-Kirad.
8. Attempt to board the airplane. You will be questioned over you knife. Reply that it is because you are a chef, and show them your food. When questioned again, mention that you are a member of the Legend's guild. They will let you on.
9. On the plane, begin making your way to the front. Many NPCs of varying strength will try to attack you, but you should fend them off until you get to the cabin. Make sure you're over 65 hp and then hijack the controls.
10. A cutscene will play in which you crash the plane into the Eterna temple, leaving you with about 3 hp regardless of your level.
11. Return to Eblis. Quest complete!

Rewards: Whatever, I dunno

Where are the Level 555 dragoons?

If you die in the plane attack, you ascend to heaven where you have 42 level 555 dragoon virgins all to yourself.

It sounds like something that jagex would have released 4 years ago.

This isn't offensive, this is just stupid.

lmfao... I got a name for it: T3R0RIZ3M FTW

I support Chris' theory

I figured out why jokes about touchy subjects are good stuff. I learnt something.

Har Har.

This subject isn't touchy for me at all. It's still a stupid quest though.

Wellduh. I don't think you can take this storyline and make a good quest out of it. Except you can. Stuff like that.

Add some conspiracies to the story.

For a second there...I thought Ninjasafe came back and posted a retarded topic...

Nice try, we already know you are Ninjasafe.

Oh man, if I were Ninjasafe, that would be awesome.

I didn't say you were Ninjasafe Bloodthir, I was simply joking that rune_low_rider was.
