Description

Astryux is the last remnant of a now dead species of Dragon. Once, the Starlight Dragons lived within the Astral Sea, soaring through its skies. Unlike their beloved stars, they were not eternal, and eventually their race withered away and died off.

Astryux fell to the material plane as a wyrmling. A frail and sickly creature, he was doomed to die, but he was found by another dragon who followed the trail left by his falling star. Lyranex, a Blue Dragon either took pity on the frail creature, or was smitten by his starlight aura. She adopted the dragon as her younger brother, and in an rarely seen display of kindness from an otherwise vain and cruel dragon took care of Astruyx.

As he grew, Astryux did not shed his sickly and physically weak body. He grew no larger than a horse, and could barely even move himself, relying heavily on the larger and stronger Blue Dragon. What he lacked in strength, he made up for in his natural prowess in his Starlight Magic. Deep underground within Lyranex's lair, Astryux shone like a star, and attracted a group of Mothrill wanderers who began worshipping the dragon, believing that one day he would usher in a new age for their people.

Lair and Lair Actions

Astryux shares his lair with his adopted sister, an Adult Blue Dragon, Lyranex. As such, he shares his lair actions with her, while having unique lair actions of his own. The Lair is located deep within the underdark, in an expansive cavern. The caverns ceiling has formed to resemble a starry night, with multitudes of luminescent crystals acting as substitutes for real stars. The cavern itself is rocky and devoid of most life. The lair proper lies within an abandoned temple set at the far edge of the cavern, overlooking the false starlit night and the barren cavern.

The Temple and Cavern is guarded by a group of Mothrill Warriors who worship Astryux as their deity, who will usher them into an Age of Starlight
