Command the Ancient Ones (Su)

Tawil at’Umr commands the obedience of a race of lesser immortals known as the ancient ones, creatures akin to itself but of inferior power. An ancient one is a hundun with the invincible mythic simple template that is native to the Material Plane. In addition to Tawil at’Umr being able to summon ancient ones to its side, any command spoken or telepathically sent from it to an ancient one (but not to a normal hundun) must be obeyed without question (and with no save).

Dimensional Dreams (Su)

When Tawil at’Umr uses its nightmare spell-like ability, it can target any creature it has affected with its spell-like or supernatural abilities, or any creature that has ever traveled via a gate spell, regardless of distance. In addition to the effects of nightmare, the target must succeed at a DC 39 Will save or die, only to be reincarnated a moment later into a new body on another world. This is a mind-affecting death effect. The save DC is Charisma-based.

Dimensional Fortification (Ex)

Tawil at’Umr cannot be forced to travel via teleportation effects unless it so chooses.

Immortality (Ex)

If Tawil at’Umr is killed, Yog-Sothoth can create a new avatar immediately. The replacement Tawil at’Umr typically does not reappear where it was killed, and it usually does not seek revenge against those who slew its predecessor. Usually.

Merge Lives (Su)

Once per day as a full-round action, Tawil at’Umr can cause a touched creature’s mind (the target) to merge with any other creature (the host) that Tawil at’Umr has affected via dimensional dreams. The target can resist this effect with a successful DC 39 Will save. If the creature fails its save, its body vanishes (leaving behind any gear it may have carried) and its mind becomes trapped in the host creature’s mind. The target can observe the world through the host creature but cannot control the host creature’s actions. In time, or under certain conditions, the target can eventually take control of the host’s actions, but these developments are rare and require hundreds of years to occur (usually, the host creature dies long before the target can exert such influence). To others, it is rarely apparent which body throughout the countless worlds Tawil at’Umr has seen was chosen as a host for the target’s mind. This is a mind-affecting curse effect. The save DC is Charisma-based.

Portal Mastery (Su)

Tawil at’Umr senses when a creature is about to teleport into its vicinity (within range of its unspeakable presence), or when a portal is about to open in that same area.

If it wishes, Tawil at’Umr can block the teleportation or portal effect from occurring as an immediate action. The creator of the effect must succeed at a caster level check against Tawil at’Umr’s spell resistance or the effect is countered.

Temporal Displacement (Su)

A creature struck by one of Tawil at’Umr’s slam attacks must succeed at a DC 39 Fortitude save or enter a state of suspended animation like that created by temporal stasis. This condition cannot be removed via dispel magic, nor does freedom of movement offer protection.

Freedom can immediately end this effect, as can Tawil at’Umr’s touch. Once every 24 hours, a displaced creature can attempt a new DC 39 Fortitude save to end the effect, but otherwise this effect is permanent. The save DCs are Charisma-based.

Unspeakable Presence (Su)

As long as it remains shrouded in its cloak, Tawil at’Umr’s unspeakable presence is suppressed, but as soon as it attacks or otherwise reveals its true form, any creature within range that fails a DC 39 Will save is placed in its own subjective reality, as if under the effects of a microcosm spell. A creature immune to mind-affecting effects that fails its save against this effect is instead staggered for 1d6 rounds. This is a mind-affecting phantasm) effect. The save DC is Charisma-based.


Environment any
Organization solitary (unique)
Treasure triple

Tawil at’Umr is unusual among the Great-Old-Ones, for it is a physical projection of the will of one of the most powerful of the Outer Gods—Yog-Sothoth. As a sort of avatar of this deity, Tawil at’Umr pursues its own goals throughout the Material Plane and dimensions that intersect it in ways mortals can never fully understand.

Tawil at’Umr is just as likely to react to attacks against it with its formidable combat prowess as it is to ignore its attackers or simply relocate to another point in the multiverse—its reasons for doing so are as inscrutable as its plans for reality. Some scholars theorize that Tawil at’Umr is little more than a side effect of Yog-Sothoth’s presence upon reality when the Outer God brushes up against this universe. Even if this is the case, Tawil at’Umr’s knowledge of reality is vast, and many have sought the avatar out to learn its secrets.

Tawil at’Umr appears as a cloaked figure of approximately the same shape as the observer, yet larger—when viewed by a humanoid, it stands 12 feet tall. When it casts its cloak aside, it is revealed as a seething mass of protoplasm capable of taking many shapes and forms, several of which should not be able to exist.

Tawil At’umr’s Cult

Very few even know about the existence of Tawil at’Umr, much less worship this Great-Old-One. Most who would venerate it instead worship it in its true form, Yog-Sothoth. Those who choose to exalt this less-powerful but highly-focused avatar tend to do so as individuals, and no organized cult to Tawil at’Umr is known to exist. Those who specifically seek to devote themselves to Tawil at’Umr typically do so out of a mistaken impression that worship matters to the avatar.

Tawil at’Umr’s symbol is a black spiral inside of a hexagon, and his favored weapon is the dagger. The Great Old One grants access to the domains of Chaos, Knowledge, Travel, and Void, and to the subdomains of Dark Tapestry, Exploration, Night, and Stars.
