The Topaz Astrolabe is the gem artifact of Tuschello the original Topaz dragon thane, serving under Sardior in the Ruby Court.
History
Before its discovery in 825 PR, it's presumed to have lived among the dragons in the Ruby Court.
It was found in a collapsing cavern wall in a mountain-side shrine just outside Maris in the Northern Snowy Mountains of Isonhound.
After being activated for the first time in millennia, the Astrolabe gave off the equivalent of dust off an old book, except in this case it was the energies of the original draconic Ruby Court, the last echoes of divine spark from a time long forgotten. When this occurred it passed that spark into the 7 heroes who had activated it: Tristram Caniedydd, Brakanar, Grandmush, Ona, Spinel, Arlin, and Draennac.
A special interaction occurred when the holy draconic energies met Arlin, who was already a devout follower of Bahamut. Rather than giving him a connection to Sardior, it awakened and enhanced his latent holy powers, transforming him into a Silver Dragonborn.
During 825 PR the Astrolabe was relocated to Gammelgard where it was set up to protect the city against The Umbral Flood. As it turned out, it's Topaz Energies could push back against the Emerald energies of the Flood, as they were conjured by an Emerald Dragon named Feredemius.
About
It looks like a hollow crystal sphere with constellations etched on the outside, while a topaz gem representing the sun magically suspends itself in the center. It is on an ornate stone base with ancient draconic language written on it.
When activated, the Topaz Astrolabe can open a portal across the stars, allowing for quick travel through the universe via the Astral Sea. This could be used to even speak to the souls of the dead if they were still lingering, such as Tuschello himself.
