Star Spawn
Starspawn refers to either of two groups of Monsters in Dungeons & Dragons, although precisely which group depends on the edition.
In Dungeons & Dragons 5th Edition, Starspawn is used as a new grouping for various Lovecraftian monsters, mostly edition upgrades of the Foulspawn and a handful of new faces, such as the D&D Worm That Walks.
The original Starspawn appeared in Dungeons & Dragons 4th Edition. Here, they were intimately tied into one of the more Lovecraftian aspects of the World Axis cosmology; long story short, the World Axis is full of stars that are sapient creatures, strange cosmic aberrations who were mostly known for serving as patrons to Warlocks, with a list fleshed out heavily in the article "Wish Upon A Star" from Dragon Magazine #366, which also features the Student of Caiphon Paragon Path and the Radiant One Epic Destiny, both tied to these dark stars. The Starspawn, as their name suggests, are cosmic aberrations born from these stars - although it can also be used to refer to the aberrant stars themselves, as Allabar, Opener of the Way, is considered a "Starspawn" in his own right. These Starspawn were detailed in the Monster Manual 2 and 3.
