[*][b][u]Personality:[/u][/b] If you wanted to pick a single word to describe Svetleaze, it would be vanity. Being an exact physical copy of Justeaze does invite a good perception of your body--if anything, it's too perfect to be human, after all--but she takes it to an unhealthy degree. For a homunculus born to fight, her anger at damage to her clothing or body is simply unreasonable, as is how fastidiously she is about her appearance.
Despite the vanity, and even despite the whole-hearted belief in her own superiority over normal magi or lesser families, the homunculus is unfailingly polite. Even in the event of beating someone in a fight and indulging her inner sadist, there's no reason to start being rude. 
[*][b][u]Abilities:[/u][/b] As a top-class Einzbern homunculus, it is completely unsurprising that Svetleaze is an unfairly good magus, made to a standard that all the careful breeding and good genes might produce once in five hundred years. Of course, being an Einzbern means that the majority of her magecraft has nothing to do with combat: whilst certainly incredibly knowledgeable about creating homunculi and magical vessels, as well as far simpler acts of material alteration, she has little magecraft fit for direct combat. Aside, that is, from something learned from one of her predecessors: the ability to shape wires with a thought. Useful for restraining, and possibly impaling, but Svetleaze has had little chance to try it out.
If things go south and she finds herself in danger, the homunculus instead has truly fearsome strength to draw upon. Having been made with combat in mind, the unsummoned Berserker's axe-sword, reinforced to not break under its own weight, is an object that she considers tiring to swing around constantly, yet not particularly heavy. Its weight also distracts from the truly precious item she carries: over five years of work have gone into layering bounded fields into the coat to absorb and distribute force regardless of where it strikes her. Practically, she might as well be wearing a suit of armour.
[*][b][u]History:[/u][/b] The Fourth Holy Grail War went terribly but it did offer some useful lessons, even for the Einzbern. One insight was that having a decoy Master was actually a remarkably effective tactic. Before they discarded it in favour of just setting up the biggest, most unstoppable Servant they could, another homunculus was created to take the role of the 'apparent' Master and divert attention away from the vessel.
Zelretch's project was a rather large distraction and, seeing as it was based around the summoning of Servants, something that they couldn't avoid getting themselves involved in and [i]definitely[/i] a scenario where their particular skills and specialities were useful simply in the construction phase. In a hunt for countless grails, the chance of finding a completed one to obtain the Third Magic is surely better than none at all.
As a result, the fake Master has found herself serving as a [i]real[/i] Master, taking the weapon fashioned from their catalyst for the disrupted Fifth Grail War along for the ride. With so many potential enemies in one place and to face, there's something intimately reassuring about a huge weapon that alchemy can't quite emulate.
[*][b][u]Other:[/u][/b] Svetleaze made her own maids. It's a shame they can't come with her.[/list]
