We propose a parameterized proxy principle from which \(\kappa\)-Souslin trees with various additional features can be constructed, regardless of the identity of \(\kappa\). We then introduce the 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 coherent \(\kappa\)-Souslin tree that applies also for \(\kappa\) inaccessible.
