Geselda was born far out into Shadow (that is, the worlds beyond the Original and the 9 Prime Shadow Worlds), the scion of a Tigerman and a human maiden. Her world was very unlike Athania, a hostile world full of magic and tech that at times meshed, others caused death and destruction unimaginable. She was fitted with techs that will work on other worlds: An armored cover for her magical eye and a force field projector that acts as armor.

Geselda, being very hot-natured, finds Athania quite warm except in the winter, so wears very little other than a sting bikini affair guaranteed to drive most men to distraction and ruin.

Her magical eye has the power of True Sight but she keeps it behind the armor to ensure she is not distracted by things spiritual until she needs it. She wears a ring of protection (+4 to saves) on her finger, bracers of defense (aka force field for DnD 1st edition) AC 3 and a bracelet of stealth (+20 to Move Silently and Hide in Shadows) on her prehensile tail.

Her sword is a mystic katana from far out in shadow, dealing 1-10 damage against man-sized creatures, for which it was forged and 1-12 against giant sized. As for bonuses, the sword has a +4 to hit bonus and she always acts as if double specialized with it in her hands, there is no damage bonus from the magic.

Being a beast-woman (cat-person), she has exceptional agility and speed, along with enhanced strength, constitution and a haste-like ability in which she has double movement rate instantly three times per day. Her senses are also very sharp so she is surprised on 1 roll on d 12.

Gesleda is primarily a fighter (F 10) but also an assassin (A5) and sorceress (MU 5) relying primarily on the blade for offense but able to call on her other skills as needed. She can assassinate as A5 and her hide in shadow and move silently with a 20% bonus as above.
