So there's a few things going on here that I don't think quite work, and I think you're wasting words.
Why this title? It seems generic, and it doesn't add very much.
Could you trade these words for something that gives me a feel for the mage character? Is he excited? Scared? Why is he performing this magic on a public street?
The "and" is a bit weird and doesn't work for me.
Overall, it's a nice enough idea, but you've not executed it as well as I think is possible. You could trim unnecessary words and then spend them on getting more character and activity into it, justifying the choice of location, and increasing the power of the language. I don't know that the ambiguity you mentioned is adding very much, either.
The Last
Why this title? It seems generic, and it doesn't add very much.
Why "once"? I presume you're interested in it being night, but is it worth spending a word? Does "it is time" really add much? Could you use something more impactful?Big Ben strikes once. It is time.
"Nameless" seems a bit of a cliche. Does "the last mage of the Illuminati" reveal something more than or different to "the last Illuminati mage"? That would save two words. We could lose the first "of magic" because "The last magic" has the same info. Are "within" or "over" necessary? "The greatest spell in human history" seems wordy. Do we need both "distilled" and "concentrated"?Nameless, the last mage of the Illuminati takes the phial of magic from within his cloak. The last magic. Distilled for over two hundred years and concentrated into the greatest spell in human history.

You already had that it was night from earlier, you don't need it again (pick one). Do you need "with it"? "Greatest" feels like hyperbole, and therefore is weaker than "great", oddly. Could strike "for man" and get two more words. Likewise "human".This night would end violence and with it war; the greatest age of enlightenment for man beckoned.
Why are they soft? Why spend a word here? More than this, I think this ending is weaker than it needs to be - the word limit has caused you to lose the character again, and these sentence fragments don't work for me. "Behind" and "Turning" impart the same information, you could drop the first one. Do we care about the fact that the phone is mobile?"Gone" is weak too. What about something active (snatched? Grabbed? Ripped away?)Behind soft footsteps. Turning, a flash of silver. Blood spills, a mobile phone gone.
And glass shatters.
