Bloomseer Poplar

 is a character at Oasis that is a part of the "Oasis" quest.

There are 3 possible ways to finish the related quest, with one of them you will be able to receive a reward from her.

You can ask Bloomseer Poplar to tell your future, and she will give you information about any of the game's named quests that you haven't found yet. For example, she describes The Superhuman Gambit as "I see a battle between ants and industry, and the men who control them!". You have to wait a couple days after asking her to see the future before this option is available again. When there are no more quests left, this dialogue option will not exist.
