Oblivion Gate clock
When the next Oblivion Gate omens, opens and seals, who guards it and what marks he bears, counting down live from your own clock.
The next gates
Every set of marks, in the order the gates come, is in the Oblivion Gate cycle, and what each mark does is in Oblivion Gate marks. A gate opens every two real hours, at 32 minutes 30 seconds past each even hour in UTC.
