A newer deeper foundation for QUeST for the universe and for MOST for the Megaverse. The basis of each is a one dimension seed and one fermion. From these roots the 256 dimension QUeST is created from BQUeST, and 512 MOST is created. BQUeST is based on a 7+1 complex quaternion space-time suggesting it is rooted in MOST. Also an extended Megaverse theory called UTMOST is created with 1024 dimensions and fermions. The foundation of UTMOST has an associated 10 dimension space evoking SuperString theory. QUeST, MOST, and UTMOST suggest a new intermediate U(8) block structuring of both dimensions and the fermion spectrums. This intermediate structure may play a role in symmetry breaking of the quaternion and octonion theories to the form of the author's Unified SuperStandard Theory (UST).
