There are many ways in which this aura manifests itself, some of these are:
The decision making process. A sub-committee meets every month, and has done so for the last one hundred and forty years, to decide upon the colour which the combination rooms curtains should be. They have yet to reach a consensus.

We could go on, questioning the clock tower with no clock; the half finished chapel which is larger than the church; the existence of new courts older than old courts; or the stipend paid by trinity college so that another college does not finish walling in a courtyard...
The Aura is immensely powerful. Any who come in contact with it seem bound to spread its Randomness to wherever they happen to settle down, regardless of where that may be...
