The Temenos piece drops from the Eastern & Northern towers (one of the central ones too, but you'd to have cleared one of the directional ones to get the chip and have access). Eastern is the one that has 4 elementals on each floor, after defeating them they each drop a chest: Time, restore, & and two "item" chests. Opening a chest makes the others disappear, so choose one! Tricky thing is that one of the "item" chests is an avatar waiting to wail on you. Northern tower has various mobs, but you can still only open 1 chest per level. Problem is the DNC item doesn't start dropping til the 3rd or 4th floor iirc.
The Apollyon piece is a bit easier to get in that it drops in all 4 zones. In my last Limbus shell those gold studs would drop to the floor constantly.
