Number 2 can be satisfied, no problem there.
Number 1 is in question: What is the definition of 'fully human'? Biologically speaking, the knight can die just like any human, being stabbed, crushed or shot will cause his demise quite splendidly. The only difference the knight has in that regard...
The character is a quintessential fairytale knight - the 'battles dragons and saves damsels' sort. A dream given form and fully believing itself to be human, even if it is truly just a facsimile.
Can I just post the updated character sheet in a new thread in the Guest Room, or am I supposed to send it to you first via PM? (The new application guidelines do not seem completely clear on that)
