She is a daughter of the Vhassars of Volantis and the fiancée of Lord Luthor Arryn of Gulltown. Her betrothal was the result of her uncle, Nyessos Vhassar, exchanging her hand in marriage for trading rights with the Lord Arryn. Along with being a model of nobility and propriety, Shekinah is known for her wit, charm, and all around sweet nature. Be careful though... this Volantene lady is merciless towards her enemies and is very effective at removing any obstacles that hinder her ambitions. Shekinah is also quite skilled in herblore and secretly has a particular fondness for playing with poisons.
Shekinah has just recently arrived in Westeros, more precisely in the Vale, and is bound to make a few friends and rivals. If you think your character(s) could have a connection with her, feel free post it and maybe suggest a plot.
Since she's marrying Lena's cousin I'm sure their's a plot between the two of them in the future, even if it's just Lena warning Shekinah of her cousin's lecherous ways.
