n. Time-Wound, a break in the flow of time

If you brought that Kel, that Elder Scroll back here... to the Tiid-Ahraan, the Time-Wound… With the Elder Scroll that was used to break Time, you may be able to... cast yourself back. To the other end of the break.

Return it here, to the Tiid-Ahraan. Then... Kelle vomindok. Nothing is certain with such things… But I believe the Scroll's bond with the Tiid-Ahraan will allow you a... a seeing, a vision of the moment of its creation.
Kelle vomindok = “The Elder Scrolls are unknown/unknowable”
(Paarthurnax, 000BD16A)

A literal scar in time, created by inhuman powers such as those of an Elder Scroll. Unknown if tiid-ahraan may also refer to larger Dragon Break events.

Compound of tiid ‘time’ and ahraan ‘wound’.
