Everywhere I read online it says that to unlock the Ixali beast tribe quests, I simply have to have finished the quest "In Pursuit of the Past", which I did many years ago, and visit the NPC named Scarlet in New Gridania. I can't seem to get the quest from Scarlet though. She just stares are me wondering why I keep harassing her.

Are there any other requirements I'm missing? Do I have to be part of the Twin Adder (I'm Maelstrom)? Not sure where to go from here
