Before leaving the Lutra realm, Grey decided to check on the three brothers he took from the horned race. He hadn't checked on them since they separated, and now he was about to leave.
There is no guarantee that they have been able to break through yet since it was a realm that has eluded those from their realm for a long time now. However, Grey had heard of people from other realms coming to the Aurora Continent to break through the barrier of their cultivation.
Unlike the Horned race's realm, the Lutra realm was a little better since they could get to the Sage Plane. If the brothers could break through, Grey would be elated for them, if not, they would have to break through in the Aurora Continent.
Having helpers had made some of his work easier, so he couldn't possibly leave without them.
Taking out the tracking device, he noticed they were all in the same location.
'It'll be easier this way.' He thought before disappearing.
