How to start rare blade Dagas side quest Lost Kingdom?

I believe I must be missing a step or prerequsite as I am running around Midorl bridge in Mor Ardain upper level at 16:00-18:00 with Kagas equipped as the "first blade" on his driver to no avail. I don't see the trigger. Do I need to max out something on his affinity chart first?


Solution 1:

There are two requirements to trigger quest - lvl 5 affinity with Dagas (Trust A or better), and corresponding time (sunset, around 4 pm).

Solution 2:

It seems you also need Pyra/Mythra in your party.
