Lana Blake is a Female Apex NPC found at the "Miniknog Stronghold" mission. She is the leader of an Apex Rebellion against The Miniknog (Big Ape), and is shown as a fierce fighter with assault rifles. At the start of the mission, she mistakes you at start as one of her other Apex soldiers, but quickly realizes you are not, but enlists in your help in stopping the Miniknog in its tracks. Towards the end she is wounded and tells you to end the Big Ape.
Once she is at the Ark, she sells a few Augments for your EPP, which is a much easier way to find them than searching through the universe. Her items change every once in a while.
