Who/what is Evelynn?

I am not simply asking what race is she, or even who she is lore wise. Rather, my train of thought is who is she suppose to be.

For the longest time I always had this vampire/lady of the night type vibe from her, or some twisted version of Janna's race. As we all know though, poor Evelynn doesn't really have a place to call her own at the moment and even less so with the rewriting of most if not all of the lore.

With her new Safecracker skin an idea came to mind...a rough shape of an idea but it's a start. What if she really was a thief? Like a genuine thief, not simply a skin for one. It doesn't take much to picture her with the roll, almost a Catwoman type thing...she pretty much has everything she needs going for her already. She has stealth but so does other champs so even though her's is permanent so to speak, it doesn't really set her apart from other stealth capable champs. The rest of her skills are well....meh! She doesn't really have an engaging play style, no epic Blitz grab moments or cross map Ashe arrows. I believe however we can give her some...to an extent! So down to the whole point of this thread is an idea that she could be the first champion to use gold in a new way. Now understand this is a rough shape as I mentioned before so bare with me (and if you have ideas to expand on it, reasons against or for, speak up). The few ideas I had in mind were these:

• Evelynn is only seen if a champion is looking at her, rather then a circle of perception around Evelynn herself (much like Kalista's sentries, players that look at where Evelynn is while she is near will see her).
• Evelynn's detection circle she currently has no longer works as is (see above). When enemy champions are within the circle and she is NOT seen she gains a move speed boost (not giving numbers, no need to complicate things)
• Evelynn's Q while stealth now pilfers gold with every champion/creep hit by "X" amount (this doesn't actually take gold away from enemy champions, back to this soon) stacking up to "X" amount. Any auto attack she makes will consume the stacks for added damage to her next auto attack and unstealth her.
• Evelynn's Q while unstealthed can work much as it does not, perhaps with some gold enhanced numbers involved.

These next two are kind of just added on and don't have a whole lot of thought put into them, take them with a grain of salt...

• Evelynn gains extra gold for killing wards, this extra gold contributes to her gold stacks.
• Players that locate Evelynn and hit her while she has pilfered gold stacks deplete some of her stacks and make a few gold.

Sorry I don't have more for other skills and such, but my thought is to take how Evelynn works now and stretch it out further, make it unique and give the Evelynn player a kind of mini game. The player will try to dash in and around her enemies, stacking her pilfered gold to make a quick sneak attack before dashing away, like a hit and run style of play but one where you must try NOT to get caught. The reason I didn't want her to actually steal gold from a player was because it feels like too much griefing and I want players to feel just as good finding her as she does trying to avoid their sight.

I am not a huge Evelynn player, but I'd like to think I care about all the champions in some way and understand the value they bring for players who love them. For you die hard Evelynn fans, I hope at the very least these ideas have sparked a few of your own and maybe we can find her a place she can call home.

Thanks for reading!
