Arriving in Undercity, Frougie met with Sylvanas and she was captivated by her and the struggles with Arthas/Lich King. Frou saw Sylvanas as a role model and aspired to follow her guidance; and in return Sylvanas saw huge potential in her an didn't hold back any training efforts, tasks or quests. Frougie drowned herself in rogue schooling with utter commitment to the ways of the forsaken rogues. Quickly Frougie excelled and was able to climb the ranking steps in combat rogues. Her expertise was in the mastery of swords and daggers where she eviscerates her enemies with fast cuts. Reaching the next level, she was introduced in the specialty of poisons use. Brewing her own poisons to coat weapons and building vanish bombs; Frou was able to perform harder quests which required her to travel to the dangerous areas of Kalimdor & Eastern kingdoms.
Based on Sylvanas orders, Frou travelled to Tarren Mill camp and Hinterland area. She met a young blood elf paladin named "soltar". Quickly both of them were attracted to one another. Although paladins & rogues have different tasks, frou/soltar managed to organize and suit their tasks around each other. After a few months, Frougie founded her own guild "The Tricksters". It was a small guild that aimed at helping each other with quests, gear, professions and gold. No real recruitment activities took place as frou did prefer to keep the guild as small as possible so that each member will receive large amounts of attention and help.
A while later, Frougie settled in Tanaris, a great desert filled with pirates, rogues, and crazed animals and of course wild troll bands. In this area she got introduced to the Goblin race, and in the city she was confused about having both members of the Alliance & the Horde in the same town. But those were the goblin rules; they acted as neutral ally to both sides. One of their strict rules demanded that NO fighting or counters would occur in their cities. Frougie had learned that the hard way. She couldn't keep up with seeing alliance and not trying to ambush them; and when she did the Goblins presented a harsh punishment. Here Frougie started to realize that horde & alliance sometimes needed to work together to reach a common goal. She understood the relation wasn't a matter of black & white or Good & evil, it's more complicated.
