nyhthavrero hyperglyph

Discovered by the crew of the deep-space transport ship Swansea Contender. Stumbled upon on a dwarf planet with a radio buoy attached to it (supposedly - nothing is certain about the Swansea Contender final transmissions).

No record about the Hyperglyph's appearance.

The final transmissions state that the artifact was taken aboard the ship.

It was 'connected' to the ship's main drive and 'new vectors' were established. Then, the Swansea Contender's crew sent the last transmission, bidding farewell to the humankind, and departed towards the unknown.

Nothing was heard of the ship, the Hyperglyph or the crew ever since. 

rronn hyperglyph

Discovered on the surface of Omicron Thriaat, a lifeless super-Earth planet in the Thrat system.

Looks like a perfectly dark pit or opening, about 25 centimeters in diameter. When observed from an angle, the void seems to be much wider than the hole. Despite that, it's more akin to a stereoscopic image - it cannot be interacted with by means of probing it or putting anything inside.

All observers had reported the feeling of being watched by 'an entity from the inside'.

Prophets hadn't acknowledged the Hyperglyph's presence - the only result of prompting them to interpret the object was an 'input error' message.

xnzrnrxn hyperglyph

First hyperglyph ever discovered. Resembles a multiplied equilateral triangle that distorts the space around it. When the observer's perspective changes, xnzrnrxn seems to 'fall' or multiply into underterminable number of sub-dimensions, similar to an infinity mirror.

Found on the moon of Garira, on a column-like protrusion at the center of a large crater.

Artificial Prophets determined that xnzrnrxn can be activated (how?) to travel to the past - but only to kill the traveler's grand-parents. Because of that, it's sometimes called the Paradox Hyperglyph.

The prophetic description of the First Hyperglyph may be as well a malfunction - an effect of the S tip of the triangle.
