[ WP ] A modern teenager is transported into a fantasy world , where they are forced into a quest with young witches and wizards their age . Fortunately , they 've got a backpack full of high-tech gizmos to help them along .

The Necromancer twirled in delight.'Another merry band of puppets for me to play with?' 
 
 I looked around and my fellow adventurers rushed in, blood, adrenaline and magic fuelling their burning passion to make history and save their village. 
 
 I watched as their swords, daggers, arrows, bolts and the like destroy their target into oblivion. 
 
 And the horror, when his true form rised from the oblivion and phased through everything. Nothing can harm him anymore. 
 
'I have surpassed my physical body long time ago, and know I finally get to unleash my true power!'' 
 
 Eventually we realised the wraith's weakness: he ca n't phase through knowledge. Tomes of the young mage made him recoil in disgust, but it was n't enough. 
 
 Time dragged by and the situation is going downhill for us. In my secluded hiding place, along with the Fated One, I winced as my new friends fell like trees struck by electricity. 
 
 Electricity. It was at this thought that I fully understood the Fated One's and my role. I would be his swordbringer, his teacher, and he shall bring down the sword on the Necromancer. 
 
 So I taught the young child electricity. How everything is made of atoms, which in turn contains electrons, how they could be used to generate an immense power. I gave him the knowledge of lightning and current. 
 
 And when the power flowed through my iPhone and replaced it's depleted battery, the Necromancer knew his time was up. 
 
 The 128GB full of PDFs, music, notes and videos wielded with supreme fluency by the Fated One came down upon him. 
 
 That is why mages can thunderstrike foes only on Book 2 of the HoSD novel series after the timeskip.
