Roaming Primals?

[Zenaku]

i thought i read somewhere that u can have the primal for 2 weeks, or you have 2 weeks to fill up the gauge. and you have to fill up the gauge with the whole group or sumtin like that

he just give out example but he said you have 1week to fill the bar then the remanding time to summon him or you lose the primal and it would return back to the world.
