The Beckoning Song

At the Solstice of Summer, the halflings of Toa gather together and group up into smaller parties. Adults and children excited and eager to show off what they have made.
All have brought minor crafts they have put together, each with the theme of a merfolk associated.
The Toan Highlands are home to many cave lagoons and beautiful Lochs. All are taught to fear the Fey of the waters, but not on the Solstice.
Halflings from all the clans make their way to any body of water they know of and lay at the banks their merfolk creations, an offering of hospitality to be share both ways.
When the water fey come for the offerings they too have brought something, the gift of their voices. Each allows a halfling to sing on their behalf. 
Music is played, food is cooked over campfires. The two peoples share an evening of merriment.
As the Solstice comes to an end the water Fey lend their song to the halflings and let them sing the past years memories into images that dance on the waters, causing ripples of memory.
These images can be found in different shapes and forms about the waters, on rocks and pebbles. Twisted images in the branches of the nearby flora.
For the water Fey they take the gifts brought to them by the Halflings, placing them into the Silent Droplet, a ancient relic from the time of the Unseelie.
Within this relic the water Fey experience stories acted out, like a puppet show. The halflings of Toa believe that their ancestors will be reborn through these crafted gifts as water Fey to one day sing with them.
The tradition is known to the halflings and water Fey as the Beckoning Song. So called after a Siren returned an elder halfling to their family, singing them back from death.
