We propose a parameterized proxy principle from whichκ-Souslin trees with various additional features can be constructed, regardless of the identity ofκ. We then introducethe microscopic approach, which is a simple method for deriving trees from instances of the proxy principle. As a demonstration, we give a construction of a uniformly coherentκ-Souslin tree that applies also forκinaccessible.We then carry out a systematic study of the consistency of instances of the proxy principle, distinguished by the vector of parameters serving as its input. Among other things, it will be shown that all known ⋄-based constructions ofκ-Souslin trees may be redirected through this new proxy principle.
