Michael's Earth 5E
Not long after the N’K invasion, Elangeline summoned the Outer Celestran Circle leadership (including Amber), and allowed them to drink of the Forever Pool. Hence, “West,” “North,” and “East” (even Furdukai) are still quite youthful more than a century later, despite the trio all being humans.
It was on that adventure that Amber, just a carrier who didn’t know she had it, passed the plague on to the Queen of Celestra. Amber became a carrier from picking it up from Lezarous, who was also a carrier. Fortunately the Queen shrugged the plague off easily, leaving her with just a few very minor scars (none on her face).
Amber’s still extremely lazy, and still spends most her time lounging around intoxicated with Furdukai.
