There is also the unspeakable visions of the seer in 85. Was there any previous mention of Trelawney and her vision-clock or am I just remembering before the update?
Yes. Trelawney has had two seer-nightmares so far, and the most recent one seems to be triggered by Harry’s (now deleted in revision) decision to apply brutal utilitarian tactics if anybody dies. The second nightmare was echoed by a Hogwarts forest centuar, a Chinese witch, and an infant in an unknown, uncivilized country.
