On another part of the Continent.
While Grey and Klaus were with Kyle, and while Reynolds was trying to get to the Peak of the Venerable Plane, Alice was also trying to do the same.
Like Reynolds, she had gotten to the Ninth stage of the Venerable Plane, but there was no way for her to improve in seclusion. She has to come out if she wants to break through.
Unlike Reynolds, she didn't need to come out, her Faction has a secret realm she could enter and break through to the Peak. If she's lucky, she might leave that place on the verge of getting to the Sovereign Plane. A month was all she needed to spend in that place, but since she's in the Ninth stage, she wouldn't need more than a week or two to get to the Peak of the Venerable Plane. After getting to the Peak, she might try to see if she could get close to breaking through while there.
