Envisioning When a bythos conveys information, it does so wordlessly through psychic projections. This acts as telepathy with a range of 100 feet but is understandable to all creatures regardless of whether they have a language. The meaning to non-aeons can be vague and is often mysterious. A bythos can use this ability to communicate flawlessly with any other aeon on the same plane.

AC 39; Fort +25, Ref +26, Will +30; +1 status to all saves vs. magic

HP 245, regeneration 15 (deactivated by chaotic); Weaknesses chaotic 15

Confusing Gaze (aura, divine, enchantment, emotion, incapacitation, mental, visual) 30 feet. A creature that ends its turn in the aura must attempt a DC 34 Will save. If it fails, it’s confused for 1 round (or 1d4 rounds on a critical failure).

Temporal Reversion [free-action] (fortune) Trigger The bythos fails or critically fails a check; Frequency once per day; Effect The bythos rerolls the triggering check and takes the better result.

Speed fly 35 feet

Melee [one-action] fist +32 (lawful, magical, reach 10 feet), Damage 2d8+16 bludgeoning plus 2d8 cold and 2d8 lawful

Divine Innate Spells DC 37; 8th augury (at will), teleport; 7th dimensional anchor, dimensional lock, haste, plane shift; 6th slow; 4th dimensional anchor (at will)

Rituals DC 37; imprisonment (temporal stasis only)

Aging Strikes [two-actions] (divine, necromancy) The bythos make two fist Strikes against a single target. If both Strikes hit, the target attempts a DC 37 Fortitude save. Creatures that don’t get weaker with age or don’t age are immune (GM’s discretion). If a creature becomes clumsy 4, drained 4, and enfeebled 4 due to Aging Strikes, it dies of old age.

Success The creature is unaffected.

Failure The creature becomes clumsy 1, drained 1, and enfeebled 1, or increases each of these conditions by 1. This effect is cumulative with other aging strikes from bythoses, to a maximum of clumsy 4, drained 4, and enfeebled 4.

Critical Failure As failure, but the creature becomes clumsy 2, drained 2, and enfeebled 2, or increases these conditions by 2.

Focused Gaze [one-action] (concentrate) The bythos focuses its gaze on a creature it can see within 30 feet. The target must attempt a save against the bythos’s confusing gaze. A bythos can’t use this ability against the same creature more than once per turn.

Temporal Flurry [two-actions] The bythos makes four fist Strikes. Its multiple attack penalty increases normally with each attack.

Temporal Strike [two-actions] (divine, conjuration, incapacitation, teleportation) The bythos touches a creature or object to displace it from time. The target attempts a DC 37 Fortitude save.

Critical Success The target is unaffected.

Success Time flows around the target; the target is slowed 1 for 1 round.

Failure The target disappears from the present moment and reappears in the same location 1d4 rounds later as if no time had passed for it. If a creature or object occupies that space when the target returns, the target appears in the closest available space to its original location.

Critical Failure As failure, but the target is slowed 1 for an extra 1d4 rounds after it returns.


The bythos is a guardian of space and time, and at all times seeks out those who misuse planar and temporal magic. A bythos is a roughly humanoid creature with four arms and a body made of swirling clouds and mist. Despite its appearance, its body feels like dry stone. A bythos seeks out paradoxes caused by irresponsible planar or dimensional travelers and repairs breaches where the barriers between planes have become thin or damaged. If the mortals responsible remain in the area and cannot be convinced to cease their activities, the bythos has no qualms about removing them. Using its ability to manipulate time, a bythos might cause an opponent to quickly die of old age as time speeds up around them, or cause a target to disappear from time and space.

Bythos aeons have no innate ability to directly enter the mysterious Dimension of Time, but many know of the hidden routes in the Great Beyond one can use to travel to this strange realm. A bythos prefers to destroy those who seek entrance to the Dimension of Time rather than risk the knowledge of how to reach it spreading too far.
