Plaster of Joining

Sealed tight, it hoards a chthonic spirit's secret of binding stone to stone.

Category: Minor

A fine ceramic urn, glazed in a wondrous blend of patterns and sheens, its snug lid clumsy to work and tricky to open once shut. It feels made for far bigger hands than yours.

Fed water, blood, reagents, and a full day and night of song, the urn yields a plaster that fuses stone, rock, or crystal into one piece. Like materials weld seamlessly; mismatched ones leave a natural gradient seam where they meet. The secret recipe and song belong to the spirit that dwells within, and it does not part with them lightly.
