Block E is the Teachers Only block. Under almost no circumstances, may students enter the block. The only allowed circumstance is when there is an emergency on the island and Master of Defence, Nekhii , approves it personally. It can be a headache to arrange accommodation for all the teachers on the TIA Campus, especially due to some rivalries between teachers due to outside politics. Master Nekhii herself lives away from Block E by one of the defence towers, along with a few other staff members connected with defence, or who simply prefer the tower to the block. Lo Chen prefers to live by himself to avoid the politics, while Ruru prefers to live by themself to be closer to the wildlife and the animals that reside in the petting zoo.
