The Guardian

Evacuate every settlement in the unmoored world to safety - Vernworth, Bakbattahl, Sacred Arbor and the rest. Talk to the NPCs in each region and lead/direct them to the safe haven before that region is destroyed by the clock (see 204135858 for how time passes). Do this before you end the cycle at the Seafloor Shrine (121731681), or any stragglers are lost for the run.
