Somnus Domina: Zagalhta’s Exolunar Collection (5th Edition Expansion)
Dungeons & Dragons 5th Edition Supplement by Logan Laidlaw

Zagalhta’s Exolunar Collection is a Kickstarter-funded 5th Edition expansion book from Nat19 that features new classes, subclasses, spells, weapons, artifacts, armor, beasts, rules for play, threats, and lore all wrapped in Nat19’s original setting, Somnus Domina! This expansion book can be used in regular games and settings, but its primary focus is JRPG-inspired science-fantasy content, including astrradecks (space ships), aliens, mecha, space gods and fiends, and more! It can be used to evoke the vibes of space opera media, including Gunbuster, Gurren Lagann, and Cowboy Bebop, as well as the aforementioned mixed-technology settings such as Final Fantasy!
Within the 385 pages of this book, you can find –
2 NEW CLASSES | 50 SUBCLASSES | 5 NEW RACES | 91 SUBRACES | 2 BACKGROUNDS | 9 FEATS | 62 ITEMS & ARTIFACTS | 112 BEASTS & NPCS | 62 NEW SPELLS | SPACE FARING SHIPS | MECHA | SPACE TRAVEL
Features VTT files for FANTASY GROUNDS and FOUNDRY VTT

This book is a work of passion for space- and science-fantasy-themed content and is intended to match the style and vibe of Nat19’s setting, Somnus Domina, but it can be used in any setting. Among its pages are the means to use or battle extradimensional aliens and spirits, space magic, use deities, swarms, and more.

Below is a quick run-through of the book:
Chapter 1 – Exolunar Space
Mechanics and details covering space travel, including the conditions of space, the ships used to do it, and personal ATV-like vehicles called liners. Also contains a section detailing rules for piloting mechs, called frame units.
Chapter 2 – People & Places
Planets, colonies, cultures, planes, and more from Somnus Domina, which also serve as examples of how to use this book’s content to create the same things for other settings or tables.
Chapter 3 – Faith & Factions
Factions that hold influence in exolunar space, including friendly and antagonistic forces, details about major and minor gods, and Luminal Minus – a major cosmic threat in Somnus Domina’s universe.
Chapter 4 – General Mechanics
New and old mechanics that serve as the backbone for “5.19th Edition,” which can be fitted into 5th Edition games as needed.
Chapter 5 – Character Options
Races, subraces, backgrounds, and feats that serve the themes and tone of the setting all build on top of Nat19’s highly versatile “Legacy Trait” system to allow for mixing and matching of racial features.
This section also includes five new races:
- The Changling, updated for Somnus Domina
- The Galvan, a species born of the Cosmic Teardrop
- The Protolife, an ooze species that assumes many forms
- The Scourage, an alien lifeform native to the Astral Plane
- The Sunling, an enduring primate species
This chapter contains 91 subraces, 2 backgrounds, and 9 feats.
All brought to life by the gorgeous art of our team, imagined through the lens of creators who grew up loving D&D, and wanted to combine it with everything they loved about their favorite inspirations. It’s all a little bit JRPG, a little bit anime, and a lot of excitement and adventure!
Chapter 6 – Class Options
This chapter contains classes, races, and new fighting styles. Its primary content are the two classes included:
- The Dragoneer, a varied, customizable class that wields the soul of a dragon
- The Frame Pilot, a class made for mecha-themed campaigns
Beyond these classes, this section contains a total of 50 subclasses for new and old classes, as well as new fighting styles.
Chapter 7 – Spells
Spells based around astral themes, including those for space travel and survival, and spells based on the use and maintenance of mechs. This section contains 62 new spells.
Chapter 8 – Treasury
New equipment, from basic armor and weapons to wondrous and magical items. This section includes artifacts from astral gods, shield generators, mech keys, relics from notable warriors, fragments of astral beasts in the form of eidolic armaments and sepherite, and more. There are 62 items listed in this section.
Chapter 9 – Threats and Hazards
Dangers found in exolunar space come in many forms. This section contains optional mechanics to employ in the depths of space, as well as rules for debris fields, and a variety of traps that can be used in and out of dungeons.
Chapter 10 – Bestiary
Finally, the bestiary contains 112 entries, ranging from exolunar soldiers to space djinn to wormhole dragons to gods and fiends. It includes beasts that can be used in space, driven as mechs, or used in traditional settings as outsiders or planar invaders. The bestiary is intentionally crafted to include content for all types of content, from horror campaigns to space-faring ones to ones inspired by Gaelic or Asian settings.
