Tales of Tolgard
Originally a gnomish secret, this alloy of copper, mithral, platinum, and silver has been adopted by the halflings and by certain elven and orc peoples near the border of the Elvish Northlands and Versat Wildlands of northern Versat. Its making remains known to few, and in many writings it is hidden behind the term _truesilver_, which has also been applied to mithral, or the phrase the trusty metal, often misunderstood by human sages to mean steel or perhaps bronze- the very mistake the writers hoped they would make.
Telstang is a dull silver in hue, rather like pewter, and is known as the singing metal because it gives off a clear bell-like tone when struck. It is non-ferromagnetic but readily forgeable, though it tends to be brittle and easily snapped off or shattered in large pieces. It never oxidizes and so lasts forever if not struck or dropped.
Telstangs shortcomings make it unsuitable for use in weapons or armor, but it is often worn, when any can be found, as bracers, buckles, brooches, pendants, and the like because of its most valuable property: Telstang and all organic material in contact with or encased in it cannot be altered in state; that is, a warrior wearing telstang and the telstang itself cannot be affected by paralyzation, polymorph spells, disintegrate, petrification, shape change and similar attacks. However, such a being also cannot be aided by beneficial magical state-altering effects such as those conferred by such spells as spider climb and water breathing.
