So here is my go at recounting the events from the first *session* (actually about a week's worth of emails).
Toria is working at her boring job in Edinburgh when she senses the influence of the Shadows at a distant tower block on the horizon. Going to a nearby park in her lunch break she finds it fenced off and being demolished by menacing figures in all over protective suits and dark goggles, who won't let anyone in to get near the boarded up building. (The building is a Shadow Infestation with 10 tokens)
She changes reality so they know her, and the gaffer lets her in while they are on their lunch break to take a look at the aquarium that they are building at the foot of the tower. Here Toria finds a distressed woman looking for her missing daughter Jenny, who she fears has got into the building site, which used to be their home. (Jenny is a Thread with 4 tokens).
Toria goes to look for Jenny, and changes reality so that the tower block is actually a development of high class flats beside the sea, with a show flat open for business. She goes in to look for Jenny, but gets distracted by the salesman trying to sell her a house by the sea. (I make this an Obsession scene, tempting her to give in to her House by the Sea obsession). She changes reality to win the lottery, and buys the house (gaining a tear), which also gives her the freedom of the building.
Leaving the salesman behind she runs off into the building site, heading up the stairs after Jenny's footsteps, and finds the girl on a precarious landing above an open shaft full of smoke and metal. She quickly changes reality so that the building (Mermaid Towers) is actually much closer to opening, with the shaft replaced by a 5 story vertical fish tank waiting to be filled. Jenny tells her that her house used to be right where the tank was, and Toria prepares to take her back to her mother.
At that moment the door of the stairs burst open and menacing Shadow minions in boiler suits and masks came rushing out, attacking them both with their gas axes (I made this a Shadow scene and had the Shadow try to un-change Toria, with a pretty severe difficulty). Toria resists with all her might (and Infestation) and a fountain of water bursts from the central shaft, flooding the entire building and all of the surrounding city. The men are washed away, as is Toria, but Jenny turns into a mermaid and drags her through the flood and out of the building.
Here they are picked up in a small boat by Jenny's mother (Iolanthe), who explains that the mermaids lived in a hidden lake where the building has now been built which was broken into by the developers, who stole the water for their building and drove the mermaids out into the sea. Iolanthe took human form and tried to stall the development, but Jenny copied her and snuck into the building while she was gone. The rest of her people are out at sea, but some, along with the 'Guardian' are maybe still trapped in the lake.
At this point Victoria has dealt with one thread and retreated from the Shadow Incursion (to an area without Taint), so it seems like a natural break in the story.
