Marana is the Master trainer for the Sneak skill. She will ask that a special coin be pickpocketed from her as a requirement to receive training from her. The Hero must be referred to her by either Mirabelle Monet, the trainer at The Fo'c's'le in Anvil or by Othrelos who has a house in the Imperial City's Elven Gardens District. She only seems to train at night. She walks around the Arboretum in the evenings.
