BABY, I'M BACK!

Summary
Mark plays as Anastasie "Tasi" Trianon, a French archeologist who was on an expedition to French Sudan in the year 1937 with her husband Salim. Following a series of supernatural disturbances, the Cassandra plane malfunctions and crashes in the middle of an Algerian desert, with Tasi waking up some time after in the back of the aircraft's remains, only to discover that Salim and the crew are missing. Hearing radio chatter coming from the cockpit, Tasi attempts to establish communication with the man on the other end, known as Doctor Metzier, but to no avail, as the receiver appears to have been destroyed in the crash. Left with no other option, Tasi reattaches the airlock's handle and exits the aircraft into the scorching desert in search for her crewmates.

Venturing outside, Tasi begins to experience visions of foregone events that appear to her as memories of the crew's whereabouts. Despite not appearing to have been alongside them, Tasi recalls that the people, with her at their side, went looking for a shelter in a nearby cave to nurse Salim's injuries. Along the way, Tasi's memories start slowly coming back to her, implying that she's suffering from a light case of amnesia. At the cave's entrance, she discovers a large slab over a stone box with some of the group's supplies next to it, before proceeding through the cave's narrow opening.

Inside, Tasi discovers an abandoned campsite with all of their belongings scattered around and, at the back of the area, a letter left by Salim recalling their situation, noting that all remaining injured passengers are now dead. Desperate and fearful of a mysterious creature lurking nearby, Salim decides to track down the rest of his companions through the mountain pass. Struggling through the mine's tunnels, Tasi hallucinates visions of distorted imagery that cloud her sanity. As she approaches a mass of floating stones and shards, the device on her wrist, appearing as a locket, starts ticking, with its speed rapidly increasing the closer she gets. Once activated, the locket opens up a portal leading to another, alien-like world, shrouded in darkness and thick mist, with its skies being accompanied by raging thunder, where time appears to have come to a halt.

After passing through the rift, Tasi traverses a steep cliff and sneaks past a number of petrified individuals while trying to avoid alerting the stalker from within the shadows. Coming to the next junction, she triggers the teleporter, only to be transported back to her home in France. Entering the child's bedroom, she finds Selim next to the crib, singing a lullaby to their daughter, Alys. But, as Tasi approaches them, the two fade out of existence, with the reality around her collapsing to reveal a crying child in the distance, nestled inside a mother's womb. Before losing consciousness, Tasi hears a child's faint voice exclaiming "momma".

Back in the human world, Tasi regains her consciousness and continues to search for her husband. Along the way, she discovers Salim's stuffed monkey that he had previously brought with him to their expedition, lying tattered on the ground. As she picks up the stuffed animal, Tasi remembers her second and current pregnancy. Moments later, after squeezing through a tight gap, Tasi breaks down in tears upon discovering the body of her recently deceased husband. Picking herself up, Tasi reads Salim's last note and takes his lantern and wedding ring as a memento of their time spent together, continuing to push deeper into the cave. Nearly escaping a cave-in, she crawls back from beneath the rubble, as a blue ball of light appears at the edge of the tunnel, guiding her to the surface.

Back outside, Mark continues to trudge through a small passage, eventually stumbling onto an abandoned French fortress. Inside the fort, he discovers a chamber from where Doctor Metzier's radio broadcast can be heard. Mark rummages through various rooms, discovering several notes and parchments discussing a mysterious mythical figure referred to as the "ashen mother", but skims through most of its contents without paying much attention. After solving the first puzzle and making his way up the staircase, Mark runs into a silhouette of an unidentified creature, before it quickly disappears behind the corner.

At the top floor, he discovers several bodies, one of them of a soldier, who appears to have committed suicide via gunshot, with the rest of the garrison being slaughtered by an unknown force. In a nearby room, there is a soldier's note that mentions Kel Hanan, a mysterious desert tribe that skins and tortures people in the name of their deity that they refer to as the "great mother". Despite the author's dislike of the group, the troop's captain seemed to be fond of them, with the soldier mentioning that they might end up killing them in the long run as a precaution. Throughout the top floor, unseen creatures walk outside Mark's field of view, bashing against doors and pulling corpses through openings in walls. Eventually, Mark fixes up an old cannon and uses its weight to destroy the lower floor's ceiling and access the radio room. After establishing radio connection, the Doctor instructs Tesi to rendezvous with him at the village by going through the mountain pass. Before he could answer the reasons behind her blackouts and the loss of control over her actions, the radio's frequency gets cluttered with static and cuts out at the end.
