Slowdrifter reporting with Aemilia Karthis, CG half-elf mesmerist [vexing trickster] 2/sorcerer [tattooed sorcerer] 1. Full profile here, including a lengthy backstory and personality section as I was having fun with it and got a bit carried away.
I ended up going with a sorcerer dip but will otherwise be full mesmerist. In terms of role she's enchantment focused, with debuffs her main weapon, and probably support and buffs in a lesser capacity. She's an excellent face and has some knowledge skills too. Probably don't ask her to swing a sword.
The basic outline is she's a beautiful, proud and beguiling Taldan noblewoman. However, as a half-elf and with something of a reputation as a troublemaker, her traditionalist family have decided the best way to deal with the embarrassment she causes is to ship her halfway round the world - problem solved! Aemilia is keen to write her name in the history books so she can return home, live the life she wants and probably rub her family's noses in her all-round greatness. Finding an abandoned city full of fabulous riches and ancient histories? How simply perfect for her designs. A number of the motivations would work well and she can be easily tweaked to fit.
