When do Edel and Veigus join the rest?

[Xexal Seyer]

They seem to start on their own island with their own dungeons away from the other characters, when do they join the other dungeons

[_muniobus_]

i believe veigas was released after labyrinth, and rather than joining the grandchase... he beat the h*ll out of all the mp/amp characters, because he believed it was his fate; a prophecy

[_muniobus_]

as of edel... i think i've never seen her dialog in any of the dungeons story

[Xaaya]

Veigas got a revelation from god saying he gotta destroy Aernas. he fought with the grand chase and as it turns out, that revelation is fake and now he wants to find who's responsible for that fake revelation. The grand chase then get sucked into a dimensional portal leading to the events of Tower of Disappearance

Edel used to be part of Knights of Serdin, the same knight division Knight Master, Isolet is part of. she went back to her place because she got a bad feeling, her family was cursed and her brother is either kidnapped or got sucked in a dimensional portal and is trapped. most likely kidnapped.

she seeked advice from the violet mage guild leader Serre, Arme's adaptive grand father. Serre told edel that arme and the team is going around sealing dimensional portals that leads to elyos, the demon world. so she joined them.
Before archimedia events starts i believe.
