The sky sphere is a magical glass ball. Inside, it shows the sky in miniature as it was in real time, changing as the sky changed. The detail was extraordinary, showing what clouds there were and what birds were flying. It would show the colors of sunset as the sun really set, show a miniature moon and tiny stars as they appeared in the night sky, and would show boiling clouds and jagged lightning when it was storming outside. It is set into a low silver stand. The sphere has its origin on the island of Dorne.
The sky sphere was created on Dorne through magic, presumably by a Fellan or part-Fellan.
Shadows of the Master
Dare Larsett found the sky sphere covered in dust in a dark corner of a tiny, out-of-the-way shop in Dorne. The sphere became Larsett's most prized possession and he always kept it on his writing desk. He took it with him when he left to seek out the Staff of Tier and traded it to Thurl, a leader of the swampdwellers on Two Moons, in exchange for a goozli.
After Britta saves the life of Stassi, one of the swamp-dwellers, Thurl attempted to offer her the sky sphere. By saving his life, Stassi was bound to serve Britta for the rest of his and she hoped Britta would accept the sky sphere instead of Stassi. Britta, recognising it as her father's, refused, fearful that Mab would also recognise it as Dare Larsett's and not wishing for there to be any link between herself and her father.
