The Bionis' Interior (巨神胎内, Kyoshin Tainai) is one of many areas featured in Xenoblade Chronicles. One can enter the Bionis' Interior from both Makna Forest and Satorl Marsh, eventually emerging at the other. At the end of the game (Chapter 17), the Bionis' Interior becomes accessible in its entirety and becomes filled with enemies and collectables.

Story

First visit

After defeating the Satorl Guardian and leaving Satorl Marsh, Shulk and friends enter the Bionis' Interior - literally inside Bionis itself. While here, Shulk mentions that Bionis still feels alive somehow.

This area is (initially) incredibly small compared to other areas and has almost no other living beings, except a single Nopon.

Revisited

After the events at Mechonis Core, following the destruction of the Mechonis, the group returns to the Bionis' Interior, now much more alive, through a wound caused by Mechonis' hand. They access the Interior Landing Site by flying in Junks. The Junks remains in place at that landmark, and its icon appears on the map.

They meet Lorithia who has Kallian. She walks into the Bionis' Heart which is where they head off to. When the group reaches the heart, Lorithia brings Kallian in his Telethia form, and says that he is now under her command. She then kisses him in order to anger Melia. Lorithia then combines with Kallian and fights the group. After Lorithia is defeated and Kallian gives his parting words, a dark teleporter to Prison Island appears, and the party steps into the teleporter to defeat Dickson.
