Femi

Femi is a gnome that you have interaction with during The Grand Tree quest. She can be found right outside of the gate leading in to the Tree Gnome Stronghold. Providing that you help her earlier in the quest, she will help you access the stronghold later when you are unable to, for free. If you did not help Femi with loading her packages, then you will be required to pay Femi 1000 coins for her help in accessing the stronghold at that time.

Femi is who you want to speak to if you receive an anagram Treasure Trail scroll with the words "ME IF".
