The Moebius Sect grounds had changed in the last few decades. Once Lind took over, he began to expand the integration of the Mengcong into the outer sect. Beasts came in all sizes and not all could change theirs either but the space needed to welcome them was large.
Lady Gua had been happy to see Lind accommodate the beasts more but not impose on the jungle around him. The trees were treated as fixed beings and were taken care of within the area circumscribed by the outer sect but no wall was constructed.
Those beasts that lived in the trees were allowed to make a place in the branches but any previous resident was not kicked out. It was chaos at first but after a decade, it was perfectly normal after each admission exam that new beasts made a home for themselves.
