  This article concerns the asymptotic geometric character of the nodal set of
the eigenfunctions of the Steklov eigenvalue problem $$ -\Delta
\phi_{\sigma_j}=0,\quad\text{ on }\Omega,\qquad\qquad \partial_\nu
\phi_{\sigma_j}=\sigma_j \phi_{\sigma_j}\quad \text{ on }\partial\Omega $$ in
two-dimensional domains $\Omega$. In particular, this paper presents a dense
family $\mathcal{A}$ of simply-connected two-dimensional domains with analytic
boundaries such that, for each $\Omega\in \mathcal{A}$, the nodal set of the
eigenfunction $\phi_{\sigma_j}$ "is $not$ dense at scale $\sigma_j^{-1}$". This
result addresses a question put forth under "Open Problem 10" in Girouard and
Polterovich, J. Spectr. Theory, 321-359 (2017). In fact, the results in the
present paper establish that, for domains $\Omega\in \mathcal{A}$, the nodal
sets of the eigenfunctions $\phi_{\sigma_j}$ associated with the eigenvalue
$\sigma_j$ have starkly different character than anticipated: they are not
dense at any shrinking scale. More precisely, for each $\Omega\in \mathcal{A}$
there is a value $r_1>0$ such that for each $j$ there is $x_j\in \Omega$ such
that $\phi_{\sigma_j}$ does not vanish on the ball of radius $r_1$ around
$x_j$.
