Starfinder Society 1-23: Psychic Echoes [1-2]
In the aftermath of the Starfinder Society’s last trip to the frozen moon of Luvoth, in *[Starfinder Society Scenario #1-02: Mystery of the Frozen Moon](https://store.paizo.com/starfinder-society-scenario-1-02-mystery-of-the-frozen-moon)*, the lu-venon citizens of Luvoth have been liberated and reunited with friends and family. In the months since, they’ve attempted to reclaim their world and rebuild their crumbling society. To temper the danger of initial explorations, lu-venon leadership decided to reach out to the Starfinder Society, requesting their assistance with exploration efforts. Your first task? Explore a mysterious ice cave overflowing with psychic activity while accompanied by lu-venon researcher and Starfinder ally, Uloa Su-Tae.
A Starfinder Society Scenario designed for 1st- through 2nd-level characters, playable in 2-3 hours.

Meaningful Conversation and Coffee - Northside Social Falls Church
**Join us in Falls Church for conversations that go beyond small talk.**
Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room.
There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique.
MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech.
Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations.

What Is The Reactive Mind? Can You Get Rid of It?
Your negative emotions can significantly impact your life and your relationships. Sometimes couples and friendships break apart simply because people couldn't manage their own negative emotions, such as anger, worries, anxiety, or depression.
In this meeting, you will learn where these negative emotions come from, for you, and what you can do to start healing from them.
YOU CAN DO SOMETHING ABOUT IT!
And you can do it without medications, without suppressing these emotions inside yourself. You don't need to leave your loved ones.
Come to this meeting and learn the answers.
This group is created by the Dianetics & Scientology life improvement information center in Washington, DC.
Profs & Pints Northern Virginia: Dune and Messiahs
[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Dune and Messiahs,”** on word of saviors in religion and science fiction, with Peter Herman, former lecturer in theology and religious studies at Marymount University and scholar of religious and social themes in sci fi.
[Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-dune-messiahs](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-dune-messiahs) .]
*Dune: Part Three* is scheduled for release in December, and trailers for the epic space opera film have fans of the *Dune* franchise longing for it like visitors to its desert planet Arrakis long for water. Based on the second volume of renowned science fiction novelist Frank Herbert's *Dune* saga, the movie depicts the internal and external conflicts of protagonist Paul Atreides, an emperor treated by others as a messiah while being depicted as an antihero.
The film will raise intriguing questions related to the presence of redeeming figures, or messiahs, throughout both science fiction and religious texts. Among them: What exactly do we mean by the term “messiah”? Why have many religious traditions looked for a redeemer to emerge? What happens if the messiah gets it all wrong?
Explore such questions—and prepare yourself to enjoy the upcoming *Dune* film at a much deeper level—with Dr. Peter Herman, who has given several excellent, thought-provoking Profs and Pints talks on the *Dune* franchise.
To center *Dune* in the discussion, we’ll look at the character of Paul Atriedes as a ruler who has launched a jihad across known space to reconquer it. His prescient visions show him that although the spread of religious war is not optimal, neither is it the worst potential future for humanity, and he allows excess and violence to continue in his name out of a conviction that it’s for the greater good. Throughout the book on which the upcoming film is based, Atriedes struggles with his followers' desire to view him as a divine figure.
Dr. Herman, a trained theologian, will set such themes in the broader context of religious studies by discussing messianic figures across various religious traditions. Among them, Christianity names Jesus of Nazareth as the messiah, but he is hardly the first person in the canonical Bible given that title. Mainstream Judaism does not anticipate any similar, deified figure descending from heaven, but messianic strains of Judaism have looked for the arrival of a political liberator. Islam, from which Frank Herbert borrowed terms applied to Paul Atriedes, contains reference to someone serving not as a redeemer but as a heavenly guide. All branches of Buddhism situate within each new age of their cyclical cosmology a Buddha-yet-to-come.
We’ll look at the human tendency in confusing times to seek out direct, uncomplicated answers and to embrace messianism as part of apocalypticism, which foretells a straightforward sorting process in which believers, as good people, see reward while their enemies, as bad people, see punishment.
*Dune* fans will feel rewarded for coming to this talk. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.
Thanks to the team at Nationwide of supporting the group.
The Completely Series
These meetings will be a building block approach to learning photographic mastery over three disciplines:
Mechanical Mastery (MM) - 13 weeks of the series
Exposure Mastery (EM) - 26 weeks of the series
Composition Mastery (CM) - A 52 week series
All three series will run concurrently and will dovetail as follows:
Q3/26 - MM (Iter 1), EM (Iter 1, Pt 1), CM (Iter 1, Pt1)
Q4/26 - MM (Iter 2), EM (Iter 1, Pt 2), CM (Iter 1, Pt2)
Q1/27 - MM (Iter 3), EM (Iter 2, Pt 1), CM (Iter 1, Pt3)
Q2/27 - MM (Iter 4), EM (Iter 2, Pt 2), CM (Iter 1, Pt4)
That's likely confusing, but essentially, MM offered 4 times in that period, EM offered 2 times, and CM offered 1 time.
**TO BE CLEAR - THERE IS NO CHARGE FOR THESE CLASSES.**
This is an aggressive series, with presentations, homework, group shoots to be added in, likely at LEAST twice a month, image critiques, and an expectation that you are willing to put in the work to elevate your photography significantly. Open to all levels and all equipment levels. Don't let hesitation about your skillset and/or gear keep you from a one-time opportunity.
The group will meet every Monday, with periodic exceptions, and we will try to keep as close as possible to the original plan. Obviously, more data to come, and will be published as this is further developed, but now is the time to decide if you want to be a part of this.
