She stands outside of Haven Castle in the Haven Castle District, and is the source of numerous Quests (as well as, if you've completed the Statue thanks to your friends, a Daily Energy Refill).

She is also the only way to gain Friend Tokens, via helping your friends in their own endeavours, which have the sole purpose of being traded with Sasha for Bush Bucks.

On a side note, rumor has it Jim the Lumberjack has a bit of a crush on Sasha...
