It doesn't seem as though Filian's decision to step away will be permanent, but fans are still a little anxious about the "what's next."

With any luck, she really is working on an ARG and someone will solve it soon. In the meantime, fan speculation will continue to run rampant on Twitch and Reddit.

One Reddit user suggested that after a certain time had elapsed, it's typical for an ARG to be revealed, writing, "From my experience with ARG’s if the community doesn’t solve it correctly or on time the creator just makes a confederate to dump a bunch of hints or just solves it outright."

For now, all fans can do is hunt for possible ARG clues, discuss the possibilities of her cryptic disappearance, and hope the mystery is solved sooner than later.
