First Appearance: TBFGK 49
She seems to have a preoccupation with fire, commenting at one point that she "rather hopes Parson Gotti will burn down the whole world." In addition, she seems to believe herself to be in an ongoing competition with death, and has proven herself to be willing and, in fact, eager to push her luck even against overwhelming odds in order to further Gobwin Knob's cause. It's unknown whether she had these attitudes in life.
Sylvia was the highest ranking Warlord in Unaroyal's contingent in the Royal Crown Coalition. She served as an advisor to Prince Ansom and was the voice for her side as a member of the Royal Crown Coalition War Council. She was one of only four warlords at Ansom's table on the penultimate night of the siege; Erf-b1-p101 - the others being Duke Nozzle, the Blue Warlord, and the Superfluous Warlord.
She retrieved the Arkenpliers from Ansom's body when he was croakedErf-b1-p132 and was in possession of them for a short whileErf-b1-p137 before she croaked along with the rest of the Royal Crown Coalition in the eruption of the volcano.
As of LIAB 86, it's be revealed that Sylvia was popped as a stabber; whether this precludes her from being a noble or royal is unclear.
Sylvia's internal monologue in LIAB Text 52 clearly identifies herself as a former Royal, "As funny as this game was in many ways, inside her there was a former Royal who had been there."
Its possible that the bargain Jojo made to rig the rules in her favor are at the expense of other units, so that they are killed so that she is allowed to live.
Real World reference
Lady Sylvia Lazarus is a reference to Sylvia Plath, who wrote a poem entitled "Lady Lazarus". The poem in LIAB Text 8 is a direct allusion to it, imitating it closely with just minor alterations to adapt it to the Erfly context.
Sylvia Plath herself used the name "Lazarus" as a reference to Lazarus of Bethany, from the Gospel of John.
