umbral era starts when urianger attacks you with his familiar and continues in the grand company questline about meteor. I guess it technically started when he started showing up at camps warning you about the umbral era if you count that as the start of a questline.

they kinda merge as the main characters from each of the main questlines are apparently friends of Urianger, but the two questlines are seperate.
Thanks, that's a big help!
