The Deep-Sky Ledger is a Very Rare D&D 5e wondrous item requiring attunement. It helps detect planar gates, identify extraplanar creatures, and can restrain foes, but inflicts exhaustion.
✨ Item Overview
Prepare to delve into the cosmic with today’s featured magic item: The Deep-Sky Ledger. This ornately bound tome, with its pulsating crystal and shimmering runes, is a nexus of planar energy, offering power to those brave enough to wield its secrets. It’s a prime example of a ‘find’ that can truly shift the balance in any campaign, appealing especially to scholars, mages, and those who seek to command the very fabric of existence.
Using The Deep-Sky Ledger in Your Game
This Very Rare wondrous item requires attunement and brings both profound advantages and significant risks. Its passive ability, Orrery’s Echo, makes you a walking compass for planar disturbances, invaluable for exploring mysterious dimensions or tracking extraplanar threats. The real power, however, lies in Skymarch Glyph. Once per short rest, you can project a binding glyph that can restrain even the most formidable foes, especially elementals, aberrations, and fiends, making it a powerful tactical asset in combat.
However, such power comes at a cost. The ledger’s drawback, Planar Strain, imposes a level of exhaustion after each use of Skymarch Glyph. This consequence means careful consideration is needed before unleashing its full potential, adding a layer of strategic depth to its use. Will you risk mental fatigue to seize victory, or save its power for when it’s truly desperate? The choice is yours, adventurer!
The Deep-Sky Ledger isn’t just a book of spells; it’s a piece of forgotten cosmic history waiting to be unraveled.

📜 Item Stats
| Type | Wondrous Item |
| Rarity | Very Rare |
| Attunement | Requires Attunement |
| Orrery’s Echo | While attuned, you always know the precise direction to the nearest planar gate or rift within 1 mile, if one exists. You also have advantage on Intelligence (Arcana) checks made to identify extraplanar creatures or magical effects related to planar travel. |
| Skymarch Glyph | As an action, once per short rest, you can project a powerful glyph of binding energy. Choose one creature you can see within 60 feet. That creature must succeed on a DC 15 Strength saving throw or be restrained until the end of your next turn. If the target is an elemental, aberration, or fiend, it has disadvantage on this saving throw. |
| Drawback | Planar Strain: After using Skymarch Glyph, you gain one level of exhaustion as your mind grapples with the ledger’s vast, chaotic energies. This exhaustion can only be removed by a long rest. |
Created by the reclusive Orrery Weavers, a sect of planar cartographers, The Deep-Sky Ledger was etched from solidified void-ash in the drifting ruins of Xylos. Its last known owner was Master Torvin, whose mind eventually shattered under the weight of its vast, chaotic knowledge. When held, the ledger hums faintly, a sound like distant, impossible stars slowly turning in a silent void.
