Because I love to give my fellow ThoughtBallooners a good challenge!
Now, don't get me wrong, writing Faiza should be hard enough as it is. She is a relatively new character, also going by the code name of Excalibur, in the pages of Captain Britain & MI:13. She has the power to control the parts of living organisms with extreme efficiency, which comes real handy since she is also a doctor. On top of that, she is also the wielder of the mythic Excalibur sword.
But wait, there's more!
A few weeks ago, Paul Cornell, the creator of Faiza, put out a call for fan fiction of characters he has created, and that he would share it with all his readers over at his blog. So that means that all entries this week will be read by Cornell (as long as the writer wants to share it with him by sending him a link to it, make sure to read the rules outlined in the previous link if you want to participate at home). Is that challenging enough for you?
