Blackstone

Blackstone is a sacred object for shrews. Leaders of Guosssim transmited it to their sons. It's this stone who make a shrew Log-a-Log. It's this stone too which authorize shrews to speak, only that wich hold it can express himself.

Manu, Log-a-log's son in "Salamandastron", lost it while he was playing with the stone. But one day, Log-a-log went to the island of the Great Inland Sea. When he was sleeping, in a wood of the island, he saw Urthwyte with the Blackstone. Thinking it was a ghost he run away. Then he asked Mara to recover it, because she was a badger, like Urthwyte. When they passed the Deepcoiler, and arrived to the Island, they discover Urthwyte, Loambudd and Ashnin. Mara told them what happened in Salamandastron and Urthwyte gave her the stone.
