A Scroll from Mauren

Objectives
Find Collin Mauren in Stormwind.

Description
Okay, now for the remote detonation part of my plan... oh, I haven't explained that yet, have I?

Okay, so the short of it is this: with a little magic, I can make it so the explosives go off while you're not around. I'm putting together a device that'll allow you to push just one button and have the NG-5 explode when you're ready.

But I need a spell from a friend in Stormwind--Collin Mauren is his name. You can find him in the mage quarter there. He's human, so he shouldn't be hard to miss.

Rewards
Upon completion of this quest you will gain:
 * 825 XP (or at level 70)
 * 75 reputation with Gnomeregan Exiles
 * 75 reputation with Stormwind

Completion
Now, this spell you need; one that will allow you detonate explosives from a distance... hmmm.
