A Hand to the Future

Getting Started
Spoiler warning: Plot and/or ending details follow.

To start the quest, talk to Aris. She will tell you she needs some magical items to make a portal so you can go to Future RuneScape.

Getting all the Items
You can get the Old Crystal by talking to the Wise Old Man. However, you must find it in three chests, if you fail to get it from one of them, a level 10 Chest creature will appear, defeat it and try another. When you get it, go to the Woodsman Tutor and talk to him about the quest. He will say you need to help him to get wood from a Giant Ent, the Ent can toss you aside, but it will never hit you. You must get behind of it, it cannot toss you when you are there, get 4 logs and give them to the tutor, he won't give the Frame just right that, you must go to Aris. A cutscene will appear where you will get the frame and attach it to the crystal, then you must get something that you don't need and throw it. You will hear "OUCH! My head!" coming from the portal, equip yourself, and jump in.

Meeting and Liberating Lance
You will appear at Seers' Castle, where the Gypsy Aris will teleport you to the Mage's dungeon. Many Animated Mannequins will appear, they are level 10, and have 200 LP, better run and not lose time with them. You will then find a Guard (Level 60). It has a Blackdragon longsword, kill him...

Strategy
It's good to attack him with melee, and with Protect From Melee prayer on, as he can hit 120 very often, get the most healing food you can, its not recommended to mage or range him as the area is very stretch and there are no safespots.

When you kill him, get the Blackdragon longsword and open Lance's cage, then your player will flee and you will control Lance, whose Mind will clarify.

The Last Battle
The last part is ridiculously easy, but a little bit of intelligence is needed to accomplish it. With Lance, you must find in which stone is the Mage and use Atomic Impact on it, do that five times, and then kill the mage using melee, go out and that's it! Quest Complete!!
