The Solstice was upon them. When the sun went down the magic began to swell, the veil between this world and the Other Side thin as vapor. Mortals could sense it, even, though they may not have a name for it. They gathered together, not realizing the animal instinct of safety in numbers.
But all around the city, from the dark parts, fae began to come together as well. Unseelie filled the city- boggarts and Red Caps and things unseen for many a year with bright eyes and sharp teeth. But they were tricksy, dangerous and malicious but no worse than they ever were. The real threat, the ever present danger this year, were the Milesian that crawled out of the sewers and tube tunnels to prowl they city. They were hunting tonight. They had eyes black and soulless, eyes too wide for their white, gaunt faces. Larger than their eyes were their mouth. The smile of needle fangs glinted in the street lights. Long arms ending with spidery, spindly fingers reached and clawed at passers by from the shadows.
There was a war in the city tonight and the nature of the foe, the Milesian, meant no bound mortal needed to be near any battle. Death would come to one or the other if a killing blow came down.
But there was hope. Seelie fae prowled the city as well, fighting for Light and Air. Even the Queen had seen fit to step through with her sword and shield. Such was the threat to the Fae way of life that the Milesian presented.
The longest day of the year dawned but the sunlight did nothing to frighten off the dark forces. The longest day of the year simply meant the things that went bump in the night were attacking in the light.
(Tag in, tag around! Open all week so check back. Have fun with your adventures. If you don't want any Milesian, there are plenty of Unseelie, too. Day or night, whichever works for you.)
